Features

• Compatible with 30 mm Cage Systems
• CP38: SM1 (1.035"-40) Internal Threading and Smooth Ø2" Outer Diameter
• CP38T: SM1 (1.035"-40) Internal Threading and SM2 (2.035"-40) External Threads
• Ideal for Mounting Cage Assemblies in Optomechanical Mounts Designed for Ø2" Optics
• Not Post Mountable

The CP38 and CP38T round cage plates are ideal for mounting small cage subassemblies into optomechanical mounts designed for Ø2" optics (such as our KS2 Ø2" kinematic mirror mount) or SM2 threads (such as our SM2-threaded lens tubes). Both plates feature an SM1-threaded (1.035"-40) hole for mounting Ø1" optics up to 0.2" (5 mm) thick. For thicker optics and accessory mounting, see our SM1-threaded lens tubes. Cage rods can be secured in each cage rod through hole by a side-located 5/64" (2.0 mm) hex setscrew. One SM1RR retaining ring is included. Please note that in order to mount a Ø1" optic in the SM1-threaded hole, two SM1RR retaining rings will be needed.

The CP38 cage plate has a smooth Ø2" outer diameter, which works well with Ø2" mounts with a setscrew, while the CP38T cage plate has SM2 (2.035"-40) external threads.
