Ø1/2" Adapters for Unmounted Optics
Adapts Ø1" Optics
Adapts 9 mm Optics
Adapts 5 mm Optics
Epoxy is used to affix optics to our small-optic adapters which are then mounted in an LMR05 mount.
Thorlabs offers these versatile mounts to adapt easily between various optic diameter standards. With options for Ø2 mm to Ø9 mm optics, as well as Ø1" optics, this family of adapters offers a wide range of solutions for adapting optics to Ø1/2" optomechanical systems, including optical mounts and lens tubes.

An Ø8.0 mm lens is epoxied into an LMRA8 Adapter and then inserted into an internally SM05-threaded component. A retaining ring can then be used to secure the LMRA8 into the SM05 threaded component.
Thorlabs' small-optic mounting adapters are designed to mount non-standard optic sizes into Ø1/2" 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. Once the optic is secured in the small-optic adapter, the new assembly is held in one of these threaded mounts using an SM05RR Retaining Ring.
Also available is the LMRA10 for Ø10 mm optics, which has an outer diameter of 18 mm, and adapters with Ø1" outer diameters or external SM1 threads that use retaining rings to hold optics between Ø5 mm and Ø20 mm. Alternatively, we offer internally threaded, post-mountable fixed mounts for mounting optics from Ø5 mm to Ø4".
Incorporating Small Optics into Lens Tube Systems
The AD1B features an internal smooth bore with a 1" mounting diameter and an external 1/2" mounting diameter compatible with Ø1/2" mounts, such as the KM05 Kinematic Mount. A nylon-tipped 8-32 setscrew (which requires a 5/64" hex key) holds the Ø1" optic securely against two contact lines machined into the inside diameter. In addition, it features a through hole with a clear aperture of Ø0.35" to accommodate Ø1" optical filters.
In conjunction with the SM05P05 External SM05 Thread to Ø1/2" Optic Mount Adapter, the AD1B can be used to mount Ø1" optical filters to the end of a Ø1/2" lens tube, allowing a user to incorporate Ø1" optical filters into a Ø1/2" lens tube system, as shown in the photo below.
