Features

These fixed adapters are designed to facilitate the integration of cylindrical components such as collimators into free-space optical setups. We offer adapters that feature external SM05 (0.535"-40), RMS (0.800"-36), or SM1 (1.035"-40) threading as well as adapters that have a smooth 1/2" or 1" outer diameter. The threaded adapters are compatible with our lens tube systems, cage systems, and numerous components in our product line. The non-kinematic unthreaded adapters are best suited for use in kinematic mirror mounts, allowing a collimated beam to be steered by the mount. Each adapter is designed so that the optical axis of the cylindrical component will be centered with respect to the outer diameter of the adapter.

In addition to these fixed adapters, we offer smooth bore and SM1-threaded (1.035"-40) kinematic collimator adapters with pitch and yaw adjustment for Ø8 mm, Ø11 mm, or Ø12 mm cylindrical components. We also offer a post-mountable kinematic mount for Ø11 mm cylindrical components, which is part of our Mini-Series line.

Align Fiber Collimators to Create Free Space Between Fibers

This Video Insight demonstrates an approach for aligning two fiber collimators, so that the collimated beam provided by one is coupled into the second with high efficiency.

Two collimators, inserted into a fiber optic setup, provide free-space access to the beam. The first collimator accepts the highly diverging light from the first fiber and outputs a free-space beam, which propagates with an approximately constant diameter to the second collimator. The second collimator accepts the free-space beam and couples that light into the second fiber. Some collimation packages, including the pair used in this demonstration, are designed for use with optical fibers and mate directly to fiber connectors.

Ideally, 100% of the light emitted by the first fiber would be coupled into the second fiber, but some light will always be lost due to reflections, scattering, absorption, and misalignment. Misalignment, typically the largest source of loss, can be minimized using the alignment and stabilization techniques described in this video.

In this demonstration, the first fiber is single mode. The optical power incident on the second collimator, as well as the power output by the second fiber, are measured. When the second fiber is multimode with a 50 µm diameter core, alignment resulted in 91% of the power incident on the second collimator being measured at the fiber output. This value was 86% when the second fiber is single mode. Some differences in collimator designs, and their effects on the characteristics of the collimated beams, are also discussed.

If you would like more information about tips, tricks, and other methods we often use in the lab, we recommend our other Video Insights. In addition, our webinars provide practical and theoretical introductions to our different products.

Fiber Collimators: Tip for Mounting with Adapters

Epoxy adapters into mounts to preserve alignment when exchanging optical connectors.
Click to Enlarge

Figure 1: The components shown above are joined using threaded interfaces. Since unscrewing the fiber connector could unintentionally loosen connections between the other components, Thorlabs suggests applying epoxy to the other two interfaces to immobilize them.

Fiber collimators are often used to introduce light into an optical setup from a fiber coupled source. Thorlabs offers a variety of fiber collimator packages, some only provide a smooth barrel (like the triplet collimators) and others have a metric thread at the end of the barrel (like the asphere collimators).

For both packages, Thorlabs typically suggests the use of an adapter with a nylon tipped set screw that holds the barrel against a two line contact.

Adapters for the external thread are available (AD1109F) that allow the user to thread the fiber collimator into a mount.

However, the use of these adapters results in a stack up of threaded interfaces (threaded fiber connector, threaded collimator, and threaded adapter). As a result, it is possible that unscrewing the fiber connector could inadvertently loosen another thread interface and create an unknown source of instability in the setup.

For this reason, Thorlabs suggests epoxying the threaded fiber collimators into the threaded mounts if that mounting mechanism is preferred.

Figure 1 indicates the assembly order and places to apply the epoxy.

hi, i can't find an adaptor to mount CFP5 on Polaris K05T1. do you have a solution for this?
jdelia  (posted 2023-09-13 09:38:22.0)
Thank you for contacting Thorlabs. The only mounting adapter we currently offer that is compatible with the CFP5- series collimators would be the AD57F, which has external SM1 threads. Since there is not an adapter to directly mount a CFP5- series collimator in an SM05 threaded mount like the POLARIS-K05T1, the best solution would be to use the AD57F and then step down to SM05 external threads using the SM1A1.

Modifying the diameter of smooth cylinder from 0.45" to be < 0.44" will make SM05PT easily to be locked in a SM05 tube using a SM05RR.

Our company is moving towards using the KAD11F adapters to align the F220APC-1550 and F220SMA-1550 collimators. It would be much preferable for these collimators to seat in a threaded adapter rather than rely on the set screw to hold them in place. Thanks!
besembeson  (posted 2015-10-01 09:40:40.0)
Response from Bweh at Thorlabs USA: That is a good idea. We will review this. For now, the AD1109F is the threaded adapter we have, which hasn't got the pitch/yaw kinematic adjustment of the KAD11F.

Could you please make a AD9.5NT? It would be super useful to mount adjustable collimators in standard mirror mounts with a non-threaded adapter! Thanks!

Thoses adapters are very usefull, but some important sizes are missing in the list : 10 mm, 12.7 mm (for fiber of various white light source) and 16 mm (Fianium and Leukos supercontinuum laser collimators). Each time I need one of them I have to machine a standard adapter.
cdaly  (posted 2013-11-14 04:21:56.0)
Response from Chris at Thorlabs: We can likely provide these bore sizes as customs for the time being. We will discuss introducing these as standard parts internally as well. Thank you very much for your detailed suggestion, I will contact you directly about your inquiry.

You should include "Collimated Laser Diode Packages" under the intended uses for AD11F, since some of your laser diode packages require the 11 mm version. Just having it under AD8F led to confusion on which part to order.

Often there are situations were it would be nice with an ADllF without a outer thread, such it was possible to mount in a KM100 holder. For instance if a CPS180 were to be used as an alignment laser. Best regards Jesper

It would be nice to have a link to the compatible mounts for this product, perhaps having one Related Products link that covers all Collimators would free up a place to put a link that covers the SM1 series mounts.

These collimator adapters are designed to mount Ø11 mm or Ø12 mm fixed collimation packages in Ø1/2" (Ø12.7 mm) smooth bore mounts. Each adapter has a split bushing design with a smooth bore center hole and an unthreaded 1/2" (12.7 mm) outer diameter. The adapter is fitted over the component and then placed into a smooth bore mount, where it is secured. When being secured within the mount, the adapter will clamp around the component due to the split bushing design, holding the component in place. 

The adapter design centers the collimator within the outer diameter, which in turn aligns the collimated beam to the center of the mount it is held in. A black dot is engraved on each adapter, opposite to the split bushing slot, to indicate the location where the adapter should be clamped within a mount.

  • External SM05 (0.535"-40) Threads
  • Smooth Bore Diameters: 3.5 mm or 4.7 mm
  • Nylon-Tipped Setscrew Secures Component

The SM05PT and AD48FA adapters are designed to mount Thorlabs' GRIN Lens Fiber Collimators or Hexagonal Light Mixing Rods, respectively, in SM05-compatible mounts, lens tubes, and cage components. Each adapter's design ensures that the center of the component is aligned with the optical axis when mounted into a SM05 lens tube. Nylon-tipped setscrews secure the component against the two lines of contact created by the double-bored mounting hole. Additionally, there are holes on opposing sides of the central bore that are mechanically compatible with our spanner wrenches listed below.

There are two methods of mounting the hexagonal rods in the AD48FA adapter. Fixing the two setscrews onto a planar side of the rod will provide more mechanical stability. Please note TIR will be interrupted where the nylon touches the planar surface of the rod. Mounting the rod with the nylon-tipped setscrews in contact with an edge of the hexagonal rod will limit the contact between the setscrew and the optical surface, improving the optical performance. It is recommended that the mixing rod be mounted centered in the mount, so that no more than 5 mm of the rod extends past the edge of the mount on either side. 

A version of these mounts with SM1 threading is available; please see the SM1PT and AD48F adapters below.

F240SMA-A Fiber Collimator with an MHP200L02 Patch Cable Secured in the AD12F Collimator Adapter
  • External SM1 (1.035"-40) Threads
  • Setscrews Secure Component in Adapter
  • Versions for Fixed Collimators, Collimated Laser Diodes, Collimation Tubes, Hexagonal Light Mixing Rods, and Other Cylindrical Components

These SM1-threaded (1.035"-40) adapters are designed to mount Ø3.5 to Ø16 mm collimators and cylindrical components in SM1-compatible mounts, lens tubes, and cage systems. Each adapter has external SM1 threads and a double-bored center hole. All adapters include setscrews with nylon tips that are used to press the collimation package against the two lines of contact created by the double bore (see the mechanical drawing to the right) and position the collimation package so that its optical axis is coincident with the center of the SM1-compatible mount in which that the adapter is placed. The size and number of setscrews included in each component is listed in the table below. 

Except for the AD8F and AD15F, each of these adapters contains holes on opposing sides of the central hole that are mechanically compatible with our SPW909 and SPW801 spanner wrenches.
