Application Idea
Epoxy is used to affix optics to our small-optic adapters which are then mounted in an LMR05 mount.

An Ø8.0 mm lens is epoxied into an LMRA8 Adapter and then inserted into an internally SM05-threaded component.
Features
- Mounts Non-Standard Optics into Our Standard Threaded Ø1/2" Optic Mounts
- Ø1/2" Adapters are Compatible with SM05 Lens Tubes
- LMRA10 Adapter Mounts into Ø18 mm Optic Mounts
- Mounts for Ø2 mm, Ø3 mm, Ø5 mm, Ø6 mm, Ø6.35 mm, Ø7 mm, Ø7.4 mm, Ø8 mm, Ø9 mm, or Ø10 mm Optics
- Glue Ports Provided to Secure Optic into Housing
Thorlabs' small-optic mounting adapters are designed to mount non-standard optic sizes into Ø1/2" or Ø18 mm Mounts. Each stainless steel adapter includes two or three reservoirs next to the lens cell to secure the lens in place with General Purpose or UV Curing epoxy. Simply place a drop or two of adhesive into each reservoir located next to the lens in the adapter. We recommend using our NOA61 UV curing adhesive and MS403-10 epoxy syringe.
The Ø1/2" Optic Mounting Adapters featured below are compatible with our LMR05 (LMR05/M) or MLH05 (MLH05/M) Lens Mounts, SM05 Lens Tubes, or 16 mm Cage Components. The LMRA10 is compatible with our LMR18 (LMR18/M) mount, AD18T adapter, or SM1AD18 adapter. Please see the table below for all compatible mounting options. Once the optic is secured in the small-optic adapter, the new assembly is held in one of these threaded mounts using an SM05RR or SM18RR Retaining Ring.
Alternatively, Thorlabs offers internally threaded, post-mountable fixed mounts, which do not require the optics to be epoxied into place, for mounting optics from Ø5 mm to Ø4".
Incorporating Small Optics into Lens Tube Systems
In addition to providing a means for mounting small optics in our LMR series of lens mounts, the LMRA series of adapters (with the exception of LMRA10) are directly compatible with our SM05 Series Lens Tubes, making it possible to insert Ø2 - Ø9 mm optics into a lens tube system.

We recently introduced some adapters that make it easier to use 5 to 20mm diameter optics with our SM1 and 30mm Cage system. We will update our web page with these additional mounting options.
Below is the link to the adapters. I have also matched the adapter to the lenses you mentioned:
http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=1746
AL1210: SM1A6T
AS1512: SM1AD15
AL1815: SM1AD18
AL2018: SM1AD20
The adapters come with two retaining rings each for holding the lens in place. You can use our adjustable spanner wrench, SPW801, to conveniently thread the retaining rings.
Please contact TechSupport@thorlabs.com if you have further questions. johannes.piel
(posted 2011-04-12 16:37:55.0) And how about adapters to SM1? I need to use 30 mm cage system and would like to adapt AL1210, AL1512, AL1815, AL2018 to SM1 or dia 1" or 25mm. But there seems to be no alternative way than do-it-youself... jjurado
(posted 2011-03-14 13:16:00.0) Javier Jurado: Response from Javier at Thorlabs to cguertin: Thank you for submitting your inquiry. We currently do not offer a direct adapter for 10 mm optics to SM05 lens tubes and mounts. However, there is a very straightforward way of mounting the ACL108 into an SM05 lens tube like the SM05L20. You can use two SM05LTRR stress-free retaining rings, one of each side of the optic, to secure the optic in place. Keep in mind, however, that he clear aperture of the lens will be slightly reduced. SM05LTRR: http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=1433&pn=SM05LTRR#1536
Alternatively, we recently added a few small optic adapters for our SM1 threaded lens tubes and mounts, including one for 10 mm diameter optics. Please follow the link for our SM1AD10 adapter below:

(posted 2011-01-10 12:46:21.0) How about a SM05 adapter for 10mm diam optics? Specifically, how would you mount ACL108 in SM05L10? |
