These fixed collimator adapters are designed to facilitate the integration of fiber optic or cylindrical components into free-space optical setups (or vice versa). We offer adapters that feature external SM05 (0.535"-40), SM1 (1.035"-40), or RMS (0.800"-36) 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. These 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 collimator 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.

Fiber Collimators: Tip for Mounting with Adapters
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.

(posted 2015-10-28 01:49:57.0) Response from Bweh at Thorlabs USA: Thanks for your feedback. This seems to be an easy modification for us to make. We will review this. jdwelle
(posted 2015-09-24 12:21:32.687) 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. user
(posted 2015-05-15 09:54:14.5) 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! cdaly
(posted 2015-05-27 03:04:59.0) Response from Chris at Thorlabs: Thank you for your feedback. We will look into the possibility of adding a 9.5mm to 1" smooth bore adapter to the current line of adapters. cafortin
(posted 2013-11-11 13:14:13.18) 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. Thorlabs
(posted 2010-10-06 23:15:26.0) Response from Javier at Thorlabs to last poster: We have added this information to the item descriptions. The required hex size is 1/16". user
(posted 2010-10-04 14:07:17.0) it would be helpful for us if we can know here which HEX wrench is needed. klee
(posted 2009-10-23 17:56:48.0) A response from Ken at Thorlabs: We have now changed "Collimated Laser Diode Packages" to "Laser Diode Modules" and added it to AD11F and AD11NT. klee
(posted 2009-10-20 17:15:08.0) A response from Ken at Thorlabs to wwu: Thank you for your feedback. We will change "Collimated Laser Diode Packages" to "Laser Diode Modules" and add to AD11F and AD11NT shortly. wwu
(posted 2009-10-20 16:20:23.0) 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. Tyler
(posted 2009-03-10 10:53:13.0) A response from Tyler at Thorlabs to Jesper: After posting your idea to our internal forum I got in touch with the mechanics BU and he said that it would be no problem to run off a few modified AD11Fs if you need them. I will have someone in our tech support department contact you with more information. Tyler
(posted 2009-03-10 08:02:09.0) A response from Tyler at Thorlabs to Jesper: Thank you for using this feedback forum to let us know about how you wish to use our products in your lab.

(posted 2009-03-10 04:25:10.0) 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 technicalmarketing
(posted 2008-01-15 11:55:55.0) We have added a link for SM1-Compatible Mounts in the family image and hope that this helps you to choose the best mount for your application. Thank you for the suggestion! acable
(posted 2007-12-31 08:05:01.0) 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. |

Click for Details
An Engraved Dot Opposite to the Slot Indicates the Region where the Adapter Should be Clamped
- Smooth 1/2" (12.7 mm) Outer Diameter
- Stainless Steel Split Bushing Design Clamps Around Component When Mounted Within Ø1/2" Mounts
- Engraved with Item # and a Dot Opposite of the Slot for Locking Location Identification
- Compatible with Ø11 mm or Ø12 mm Fixed Collimators, Laser Diode Modules, or Other Cylindrical Components
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.
