Thorlabs offers SM05 (0.535"-40) threaded cage plates and 16 mm cage cubes, which allow SM05 Lens Tubes to be integrated into 16 mm or 30 mm Cage Systems. We also offer SM1 and SM2 threaded cage plates.

This SM05-Threaded Cage Plate is designed for use with our compact 16 mm cage assembly system. It features four through-holes that accept Ø4 mm cage rods. Each cage rod through hole is accompanied by a side-located locking 4-40 setscrew, which can be secured using a 0.05" (1.3 mm) hex key. Both a 4-40 and an M3 tapped hole are featured on opposite sides. In addition, 3-48 cap screws (included with cube) can be used to bolt the cage plate onto the SC6W six-way cage cube. Two SM05RR retaining rings are included.

The CP32 cage plate allows for
Ø1/2" lens tubes to be integrated
in 30 mm cage systems.
The CP32(/M) is 0.35" thick with a center-located SM05 (0.535"-40) threaded bore that is compatible with our popular Ø1/2" lens tubes. The bore can also directly accept a Ø1/2" optic up to 0.2" (5 mm) thick. Two SM05RR retaining rings are included.
Each cage rod through hole is accompanied by a side-located locking 4-40 setscrew, which can be secured using a 5/64" (2 mm) hex key. For additional convenience, an 8-32 (M4) tapped hole is provided for post mounting applications.
Thorlabs' 16 mm Removable Cage Segment Plates provide the means to extract a portion of a cage system and replace it with other pre-aligned segments, as illustrated in the photo to the right. These cage plates add versatility to a cage system without disturbing any pre-aligned components while maintaining the rigidity of the cage system. They are equipped with a flexure cam lock to hold the cage plate in position prior to final tightening via the included 3-48 (M2) hex head screws. The cage plates may be mounted on our Mini-Series Posts via a 4-40 (M3) mounting hole.
For additional information, please see the complete product presentation.
The SP05(/M) cage plate provides a convenient means for coupling 16 mm and 30 mm cage assemblies (see image to the right). The Ø4 mm SR rod and Ø6 mm ER rod holes are each accompanied by a side-located locking 4-40 setscrew, which can be secured using a 0.05" hex key (Item # HK050). The SP05(/M) also has an 8-32 (M4) tapped hole for post-mounting and a centered SM05 (0.535"-40) tapped bore (SM05RR retaining rings sold separately). This cage plate offers tight tolerances on the cage rod holes to ensure that both the 30 mm and 16 mm cage segments are centered around the central SM05 bore.
Additionally, two of these cage plates can be used to straddle a 16 mm cage subassembly in such a way that the entire assembly [SP05(/M), 16 mm subsystem, and SP05(/M)] can slide along the 30 mm cage rods as a single optomechanical unit.
The QRC05A cage mount is equipped with a unique spring-loaded dovetail design used to engage cage rods for positioning. By simply squeezing the dovetails together via the cupped actuator levers, the dovetail mechanism disengages the cage rods, allowing the mount to be either quickly repositioned or completely removed from a cage assembly. This convenient one-handed mechanism does not require any additional tools to actuate the clamping mechanism.
Cage cubes are key components of our optomechanical cage assemblies. They are an ideal way to join multiple subsystems via a centrally located interface. These components can also act as an instrumentation box for small electro-optical components. The solid one-piece construction, machined parallel and perpendicular to within 0.002" (0.05 mm), maintains excellent alignment of joined subsystems. A nylon-tipped 4-40 setscrew with 0.050" hex is provided for holding an SPM2 prism mount in place. Twelve 3-48 cap screws with 5/64" (2.0 mm) hex are included for attaching 16 mm cage plates.
