These fiber collimation packages are pre-aligned to collimate light from an SMA905-terminated fiber with diffraction-limited performance. Because these fiber collimators have no movable parts, they are compact and easy to integrate into an existing setup. Due to chromatic aberration, the effective focal length (EFL) of the aspheric lens is wavelength dependent. The design wavelength indicates the wavelength of ideal beam divergence (see the Divergence Plots and Calculations tabs for more information). Collimation packages at select design wavelengths are available with different collimated beam diameters. Select a wavelength from the quick links table to the right for details.

A fiber collimator and mounted asphere focus light exiting a patch cable using the AD1109F adapter.

The aspheric lens is factory aligned for collimation at the design wavelength when connected to its specified single mode fiber patch cable. In addition, the aspheric lens has an AR coating on both sides that minimizes surface reflections. For some applications they may also be used at other wavelengths within the AR coating range; please refer to the theoretical divergence plot for each collimator to determine if it is appropriate for your application. The operating temperature range for these collimators is -40 °C to 93 °C. Please note that these collimation packages are not vacuum compatible. Collimation packages with custom alignment wavelengths, operating temperature ranges, or vacuum compatibility are available by contacting Tech Support.

These fiber collimators are intended for use with single mode patch cables but can also be used with small-core, low-NA, multimode fiber optic patch cables. For improved performance, we recommend using these collimators with our AR-coated multimode patch cables. These cables feature an antireflective coating on one fiber end for increased transmission and improved return loss at the fiber-to-free-space interface. Please note performance specifications are guaranteed only when used with single mode fiber.

To mount these fiber collimation packages, we recommend using our collimator mounting adapters, including our kinematic collimator mounting adapters that provide pitch and yaw adjustment. In addition to Ø1/2" and Ø1" unthreaded versions, options are available with external SM05 (0.535"-40), RMS (0.800"-36), or SM1 (1.035"-40) threading. The collimation packages with external M12 x 0.5 threading can be mounted directly into our cage plate CP1TM12(/M) to be integrated into our 30 mm cage systems.

Mid-IR Collimators
For our collimators with an alignment wavelength of 3.45 µm and 4.55 µm, we manufacture fluoride fiber patch cables. Although these collimators are factory aligned for a specific wavelength, they have low divergence angles over a broad range of wavelengths. Therefore, they may be used at other wavelengths within the AR coating range. Please refer to the theoretical divergence plot for each collimator to determine if it is appropriate for your application.

Alternatives
We also offer a line of adjustable collimation packages called FiberPorts that are well suited for a wide range of wavelengths. These are ideal solutions for adjustable, compact fiber couplers. For other collimation and coupling options, please see our Collimator Guide tab or contact Tech Support.

where D and f must be in the same units.

Divergence Angle Comparison

The divergence angle can be estimated using the formula shown to the right, given that the light emerging from the fiber has a Gaussian intensity profile. This formula works well for single mode fibers but will underestimate the divergence angle for multimode fibers where the light emerging from the fiber has a non-Gaussian intensity profile. 

Simulations of the theoretical divergence when using one of our standard collimators at wavelengths other than the design wavelength are shown in the graphs below. For example, if you need to collimate 700 nm light from a fiber into a ~1.5 mm diameter beam, the F240SMA-780 collimator (represented by the '-780' line in the F240 graph below) can be used but will provide a higher divergence than at its design wavelength of 780 nm. Individual theoretical divergence plots and raw data are also available below for each collimator. Please contact Tech Support to request a collimator aligned at a custom wavelength.

Theoretical Approximation of the Divergence Angle

The beam diameter as a function of propagation distance was simulated for each of our collimators at the design wavelength, assuming input from the design fiber and a Gaussian intensity profile. The design wavelength and fiber are specified in the caption for each graph.

Theoretical Approximation of the Divergence Angle

The full-angle beam divergence listed in the specifications tables is the theoretically-calculated value associated with the fiber collimator. This divergence angle is easy to approximate theoretically using the formula below as long as the light emerging from the fiber has a Gaussian intensity profile. Consequently, the formula works well for single mode fibers, but it will underestimate the divergence angle for multimode (MM) fibers since the light emerging from a multimode fiber has a non-Gaussian intensity profile.

The Full Divergence Angle (in degrees) is given by

Divergence Angle Equation

where MFD is the mode field diameter and f is the focal length of the collimator. (Note: MFD and f must have the same units in this equation).

Example:

When the F220FC-A collimator (f ≈ 11.0 mm; not exact since the design wavelength is 543 nm) is used to collimate 515 nm light emerging from a 460HP fiber (MFD = 3.5 µm), the divergence angle is approximately given by

θ ≈ (0.0035 mm / 11.0 mm) x (180 / pi) = 0.018°.

When the beam divergence angle was measured for the F220FC-A collimator, a 460HP fiber was used with 543 nm light. The result was a divergence angle of 0.018°.

Theoretical Approximation of the Output Beam Diameter

The output beam diameter can be approximated from

Output Beam Diameter Equation

where λ is the wavelength of light being used, MFD is the mode field diameter, and f is the focal length of the collimator. (Note: MFD and f must have the same units in this equation).

Example:

When the F240FC-1550 collimator (f = 8.18 mm) is used with the P1-SMF28E-FC-1 patch cable (MFD = 10.4 µm) and 1550 nm light, the output beam diameter is

d ≈ (4)(0.00155 mm)[8.18 mm / (pi · 0.0104 mm)] = 1.55 mm.

Theoretical Approximation of the Maximum Waist Distance

The maximum waist distance, which is the furthest distance from the lens the waist can be located in order to maintain collimation, may be approximated by

Max Waist Distance Calculation

where f is the focal length of the collimator, λ is the wavelength of light used, and MFD is the mode field diameter. (Note: MFD and f must have the same units in this equation).

Example:

When the F220FC-532 collimator (f = 10.9 mm) is used with the P1-460B-FC-1 patch cable (MFD ≈ 4.0 µm; calculated approximate value) and 532 nm light, then the maximum waist distance is approximately

zmax ≈ 10.9 mm + [2 · (10.9 mm)2 · 0.000532 mm] / [pi · (0.004 mm)2] = 2526 mm.

Hello, thank you for contacting Thorlabs. This may be feasible as a custom-aligned collimator, though aspheric lenses are often not ideal for imaging. Objective lenses or GRIN lenses would be better suited to image a fiber end face. We will reach out to you directly to discuss a possible customization.

Dear Sir or Madam, We are looking for a collimator capable of collimating broadband light exiting an SMA fiber. The wavelengths we intend to cover lie between 200 and 800 nm approximately. Transmission above 50% for the whole wavelength range would be highly preferable. Would any of the fixed focus collimators offered by Thorlabs meet this requirement? Also, are the front and backside of the collimator both SMA-compatible? That is, could it function as a connector between a male and female SMA thread? We intend to use the collimator as a connection between an optical fiber and the input of an echelle spectrometer. Thanks in advance.
besembeson  (posted 2016-03-04 01:33:13.0)
Response from Bweh at Thorlabs USA: These can be used but the performance (degree of collimation and throughput) will vary over the wavelength range. These are manufactured with the lens position optimized for minimum divergence at a single wavelength. They are also AR coated to have excellent throughput over different wavelength ranges as indicated. The fiber input end has SMA connector while the output end has either M11x0.5 or M12x0.5 thread and we provide various adapters to connect to other components.

besembeson  (posted 2015-02-18 08:02:49.0)
Response from Bweh at Thorlabs USA: The lens used in the F671SMA-405 is made from ECO-550 which has very poor transmission at 280nm so we would not recommend this for that wavelength. I will share the transmission graph with you by email and look into alternatives for your application.
tcohen  (posted 2012-06-27 15:04:00.0)
Response from Tim at Thorlabs: The short answer is no, I would not recommend this part for 40W. There are a few things we need to look at in order to determine the power handling capability. First let’s look at the collimating lens. We see from the table that the lens in the F220SMA-780 is AR coated D-K59. These collimators also utilize epoxy. A conservative estimate we have for these lenses is approximately ~100W/cm^2. Let’s say your power is 40W and your beam diameter is 1mm. We then see that the power density is 40W/.05cm*.05cm*pi or 5093W/cm^2 (1mm BD). Now let us turn our attention to the fiber and the connector. A rough estimate for standard fiber is 10-15mW/um^2 and a typical threshold for our standard connectors is 2W. Whether you are collimating or coupling will also alter the damage threshold. If you use a wavelength of 808nm, you can expect to see ~10um chromatic focal length shift from a 780nm collimator. If focal shifts are present, coupling efficiency will be reduced and therefore so will the damage threshold. We do have high power fiber cables with SMA connectors rated to 50W: http://www.thorlabs.de/NewGroupPage9.cfm?ObjectGroup_ID=4393. To summarize our three parameters: standard connectors would not be suitable. Most standard fiber would not be suitable as well. High power connectors and fiber would be needed for this application, and even with this, we can see that the third item of interest, the collimator itself, is still a limiting factor. I will contact you to discuss other ways to collimate your source.

Response from Tim at Thorlabs: Thank you for your feedback.

I will contact you directly to discuss the options that may suit your application.

The F220XXX-780 and F240XXX-780 use the same lenses as found in the F220XXX-B and F240XXX-B respectively and it seems that the raw data was mistakenly linked to them. The chromatic focal length shift for the lens will be the same. However, they should be zeroed at the design wavelength for clarity. Thank you for pointing this out!

Does Thorlabs -or somone else- have data about coaxiality of the collimators (SMA and FC)?
tcohen  (posted 2012-03-21 14:46:00.0)
Response from Tim at Thorlabs: Thank you for your feedback. If you are using a fiber coupled laser which you are collimating, please make sure that the NA of the lens is equal or greater than the NA of the fiber to reduce loss. The lens has an AR coating and is produced from D-K59 glass which at the design wavelength will have >99% transmission. However, if you are planning to use this to couple into fiber, you will have some coupling efficiency which will reduce your power. I have contacted you to discuss this further.

Dear Sir/Madamm Recently I bought 3 SMA's collimator (F220SMA-780) in order to measure the power applied by a laser. I would appretiate if you could send me information about the atenuation introduced by the collimater. Kind Regards Andreu
tcohen  (posted 2012-03-08 13:07:00.0)
Response from Tim at Thorlabs: Thank you for your feedback. Using the F240FC-780 outside of the design wavelength will cause a slight focal length shift. This will alter your coupling efficiency. However, for your application it seems that the F240FC-780 will meet your needs. Please note that it is still recommended to keep your focused spot size and NA of the collimator equal to or smaller than the MFD and NA of the fiber respectively.

bdada  (posted 2012-01-31 23:39:00.0)
Response from Buki at Thorlabs: Thank you for using our feedback forum. You are correct that for maximum coupling, the focus spot size should be exactly the same as the MFD of the SM fiber. However, in reality, this is not always a possibility because the selection of the focal length is not continuous. One would then have to choose the closest focal length lens available. We have contacted you to continue this discussion.
niels.martinsen  (posted 2011-12-30 14:55:17.0)
Hi! In the "Overview" it is stated that: “To obtain a high coupling efficiency, the NA of the patch cable needs to be greater than or equal to the NA of the collimator, and the diameter of the focused beam needs to be smaller than the MFD/core of the fiber. […].” I understand that the beam width cannot exceed the fiber diameter, but why is the beam allowed to have a width less than the MFD of the fiber? Shouldn’t it ideally be equal to the MFD in order to maximize efficiency?

user  (posted 2010-04-04 16:18:41.0)
Your AR coating curves are simply not believable, the broadband curves indicate something less than 0.05% on either end, and then the V-coat at 405 nm seems to go to zero. The one that looks believable is the 1064 nm coating with a roughly 0.08% with the center wavelength (minimum) being shifted slightly from the design wavelength. It would be helpful to have vertical scales that allowed the read to understand the residual reflectivity, and ideally the V-coats would have the same vertical scales. Please review and confirm that your curves are updated and accurate.

Can you please include little labels that contain the part numbers that we can adhere to the barrels of the collimators when we receive them? Better yet, can you label them somehow (acid-etch, ink, whatever)? I have a drawer full of (unlabeled) collimators that I have no time to characterize. Had I known that they were not labeled, I would have labeled them the moment I opened the plastic pouches! But alas, its now too late for me. However maybe this message can save future generations from the same fate . . . Thanks.

Fiber Collimator Selection Guide

Click on the collimator type or photo to view more information about each type of collimator.

Type   Description
Fixed FC, APC, or SMA Fiber Collimators Fixed SMA Fiber Collimator These fiber collimation packages are pre-aligned to collimate light from an FC/PC-, FC/APC-, or SMA-terminated fiber. Each collimation package is factory aligned to provide diffraction-limited performance for wavelengths ranging from 405 nm to 4.55 µm. Although it is possible to use the collimator at detuned wavelengths, they will only perform optimally at the design wavelength due to chromatic aberration, which causes the effective focal length of the aspheric lens to have a wavelength dependence.
Air-Spaced Doublet, Large Beam Collimators Air-Spaced Doublet Fiber Collimator For large beam diameters (Ø5.3 - Ø8.5 mm), Thorlabs offers FC/APC, FC/PC, and SMA air-spaced doublet collimators. These collimation packages are pre-aligned at the factory to collimate a laser beam propagating from the tip of an FC or SMA-terminated fiber and provide diffraction-limited performance at the design wavelength.
Triplet Collimators Triplet Fiber Collimator Thorlabs' High Quality Triplet Fiber Collimation packages use air-spaced triplet lenses that offer superior beam quality performance when compared to aspheric lens collimators. The benefits of the low-aberration triplet design include an M2 term closer to 1 (Gaussian), less divergence, and less wavefront error.
Achromatic Collimators for Multimode Fiber Triplet Fiber Collimator Thorlabs' High-NA Achromatic Collimators pair a meniscus lens with an achromatic doublet for high performance across the visible spectrum with low spherical aberration. Designed for use with high-NA multimode fiber, these collimators are ideal for Optogenetics and Fiber Photometry applications.
Reflective Collimators Reflective Fiber Collimator Thorlabs' metallic-coated Reflective Collimators are based on a 90° off-axis parabolic mirror. Mirrors, unlike lenses, have a focal length that remains constant over a broad wavelength range. Due to this intrinsic property, a parabolic mirror collimator does not need to be adjusted to accommodate various wavelengths of light, making them ideal for use with polychromatic light. Our reflective collimators are ideal for single-mode fiber.
FiberPorts Fiberport Fiber Collimator These compact, ultra-stable FiberPort micropositioners provide an easy-to-use, stable platform for coupling light into and out of FC/PC, FC/APC, or SMA terminated optical fibers. It can be used with single mode, multimode, or PM fibers and can be mounted onto a post, stage, platform, or laser. The built-in aspheric or achromatic lens is available with five different AR coatings and has five degrees of alignment adjustment (3 translational and 2 pitch). The compact size and long-term alignment stability make the FiberPort an ideal solution for fiber coupling, collimation, or incorporation into OEM systems.
Adjustable Fiber Collimators Adjustable Fiber Collimator These collimators are designed to connect onto the end of an FC/PC or FC/APC connector and contain an AR-coated aspheric lens. The distance between the aspheric lens and the tip of the FC-terminated fiber can be adjusted to compensate for focal length changes or to recollimate the beam at the wavelength and distance of interest.
Large Beam Fiber Collimators large beam collimators Thorlabs' Large-Beam Fiber Collimators are designed with an effective focal length (EFL) of 40 mm or 80 mm, have optical elements broadband AR coated for one of three wavelength ranges, and are available with FC/PC, FC/APC, or SMA905 connectors. A four-element, air-spaced lens design produces superior beam quality (M2 close to 1) and less wavefront error when compared to aspheric lens collimators. As a result, these collimators are very flexible; they can be used as free-space collimators or couplers. They may also be used over a long distance in pairs, which allows the free-space beam to be manipulated prior to entering the second collimator and may be useful in long-distance communications applications.
Zoom Fiber Collimators Zoom Fiber Collimator These collimators provide a variable focal length between 6 and 18 mm, while maintaining the collimation of the beam. As a result, the size of the beam can be changed without altering the collimation. This universal device saves time previously spent searching for the best suited fixed fiber collimator and has a very broad range of applications. They are offered with FC/PC, FC/APC, or SMA905 connectors with three different antireflection wavelength ranges to choose from.
Pigtailed Collimators Pigtailed Fiber Collimator Our pigtailed collimators come with one meter of either single mode or multimode fiber, have the fiber and AR-coated aspheric lens rigidly potted inside the stainless steel housing, and are collimated at one of six wavelengths: 532, 830, 1030, 1064, 1310, or 1550 nm. Although it is possible to use the collimator at any wavelength within the coating range, the coupling loss will increase as the wavelength is detuned from the design wavelength.
GRIN Fiber Collimators GRIN Fiber Collimator Thorlabs offers gradient index (GRIN) fiber collimators that are aligned at a variety of wavelengths from 630 to 1550 nm and have either FC terminated, APC terminated, or unterminated fibers. Our GRIN collimators feature a Ø1.8 mm clear aperture, are AR-coated to ensure low back reflection into the fiber, and are coupled to standard single mode or graded-index multimode fibers.
GRIN Lenses GRIN Lens These graded-index (GRIN) lenses are AR coated for applications at 630, 830, 1060, 1300, or 1560 nm that require light to propagate through one fiber, then through a free-space optical system, and finally back into another fiber. They are also useful for coupling light from laser diodes into fibers, coupling the output of a fiber into a detector, or collimating laser light. Our GRIN lenses are designed to be used with our Pigtailed Glass Ferrules and GRIN/Ferrule sleeves.
