Features

  • Provides Collimation and Focusing of Fiber-Coupled Light
  • Designed for Easy Integration with Pigtailed Ferrules
  • 630, 1300, and 1560 nm Versions are AR Coated
  • 8° or 0° Face Angle
  • Ideal for Telecom Applications

Thorlabs' family of single wavelength graded-index (GRIN) lenses has been specially designed to be paired with our bare or single mode (SM) with connectors or our polarization-maintaining (PM) with connectors pigtailed ferrules. In contrast to our pigtailed aspheric lenses and jacketed GRIN collimators, this product family allows the combination of GRIN lens and optionally terminated pigtailed ferrule to be individually chosen, satisfying a wide range of experimental requirements. Please see the Collimator Assembly tab above for all GRIN lenses that are compatible with our pigtailed ferrules. See our broadband GRIN lenses for imaging applications.

GRIN lenses are generally used to collimate or reimage the output of a fiber. Typical applications include coupling the output of diode lasers into fibers, focusing laser light onto a detector, or collimating laser light. The lenses listed here are designed for a central wavelength of 630, 830, 1060, 1300, or 1560 nm, and are available with either an 8° or 0° face angle. The 8° versions maximize the return loss by back reflecting the incident light at a non-normal angle and are recommended for building collimators. In contrast, the 0° versions are easier to align but are only recommended for general fiber-to-fiber coupling. The 630, 1300, and 1560 nm lenses additionally feature an AR coating that reduces reflections at the interfaces to below 0.2% at the specified wavelengths, minimizing back reflections and insertion losses. Our line of pigtailed ferrules provides an 8° or 0° face angle that is designed to match the GRIN lenses. 

GRIN lenses do not require an air gap to function since the operation of the lens is due to varying indices in the lens itself, rather than the difference in indices between the air and lens. Additionally, in a GRIN lens, all optical paths (refractive index multiplied by distance) are the same due to the radially varying refractive index, in contrast to a spherical or aspheric lens. For information on how to calculate the refractive index as a function of radius, please see the Specs tab.

A ray incident on the front surface of a GRIN lens follows a sinusoidal path along the rod. The "pitch" of the lens is the fraction of a full sinusoidal period that the ray traverses in the lens (i.e., a lens with a pitch of 0.25 has a length equal to 1/4 of a sine wave, which would collimate a point source at the surface of the lens). Our GRIN lenses feature pitches of 0.23 and 0.29, which are just short of focus and just past focus, respectively. For ray diagrams detailing how lenses with different pitches are used, please see the Ray Diagrams tab.

Zero Degree End Faced Lens
The 0.29 pitch lenses include 0° end faces.
GRIN Lens with Facet Angle
The 0.23 pitch lenses include an 8° angled facet to minimize back reflection and compensate for the angular beam deviation from angled fiber ferrules.

  • The "pitch" of the lens is the fraction of a full sinusoidal period that the ray traverses in the lens (i.e., a lens with a pitch of 0.25 has a length equal to 1/4 of a sine wave, which would collimate a point source located at the surface of the lens).
  • Measured from the principal plane to the edge of the lens plus the working distance.
  • The working distance is the distance between the edge of the lens and the focus.
  • Lens Outer Diameter. Tolerance: +0.005/-0.010 mm.
  • These lenses are AR coated for the 1250 - 1650 nm spectral range and offer Ravg ≤ 0.2% over this range.
GRIN Lens Refractive Index Variation

Index as a Function of Radius
The index as a function of radius, as shown in the diagram to the right, may be calculated with the equation:
Index as a Function of Radius
where n1 is the index of refraction on the optical axis, √A is the gradient constant, and r is the radial position (ranging from -D/2 to +D/2, where D is the diameter).

Relating Pitch and Lens Length
The pitch and length of a GRIN lens may be related using the following equation:
Relating Pitch and Lenght
where P is the pitch of the lens and Z is the length of the lens.

The following ray diagrams are results from ZEMAX and are designed to show the uses of Thorlabs' GRIN lenses for various fiber coupling and collimating applications. For more details on the suitablilty for a GRIN lens to a particular application, please contact Technical Support.

Using GRIN Lenses to Collimate Pigtailed Ferrules

All pigtailed ferrules can be collimated using our selection of GRIN Lenses along with a 51-2800-1800 mating sleeve, available below. This collimator can be assembled by inserting the lens and ferrule into opposing sides of the mating sleeve as shown in the images to the right. Gently bring them into contact to ensure that the faces are parallel, then bring the lens and ferrule apart until the desired focusing is achieved.

The SMPF01 and PMPFX series of pigtailed glass ferrules have an 8° face angle which is compatible with the 8° face angle of the GRIN23 series of lenses. The SMPF02 series of ferrules have a 0° face angle which is compatible with the 0° face angle of the GRIN29 lens series.

Use the table below to select between our PM and SM pigtailed ferrules and the corresponding compatible GRIN lenses. Our PM glass ferrules are offered with FC/PC or FC/APC connectors while our SM ferrules are offered with both of these connector types or without a connector.

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 three 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 over three different wavelength ranges and are available with FC/PC or FC/APC connectors. A four-element, air-spaced lens design produces a 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 collimator or coupler. 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.

Hi I was just wondering if you have any figures for the insertion loss for using this GRIN lense to couple two fibres such as pigtailed fibres such as SM600?
jlow  (posted 2014-01-23 04:41:30.0)
Response from Jeremy at Thorlabs: There are a lot of things that go into creating a good coupling situation. As a general rule it is fairly easy to get 50% coupling (3dB loss) and you can get 90% coupling (~0.46dB loss) if you have a very good fixtures. On our single mode GRIN fiber collimator page, we also added some experimental data of pair performance insertion loss as a function of separation distance to give an idea of how these perform: http://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1340.

Single Wavelength GRIN Lenses

These GRIN lenses are designed for use at 630, 830, 1060, 1300, or 1560 nm. The 1300 nm and 1560 nm lenses are particularly suited for telecom applications due to their ease of use with small beams and negligible chromatic aberration over telecom wavelengths. Additionally, the 1300 nm and 1560 nm lenses have a broadband AR coating that reduces reflectivity of the interfaces to ≤0.2% over 1250 - 1650 nm. The GRIN2306A also has a V coating for 630 nm.
