Clamps for Aluminum Lens Tube Covers
Two C128CC clamps secure an aluminum lens tube cover between a right-angle cage mount and a high-power beamsplitter cube to create an enclosed beam path.

The C128CC can be mounted onto any 30 mm cage-compatible component with 4-40 cage rod mounting holes.
These clamps are designed to enable easy placement and removal of aluminum lens tube covers in optical systems. To remove a cover, simply unscrew the clamping screw(s), open the mount, and lift the tube out. This feature is useful for users who do not have the room to slide the entire cover out of a mount due to tight space constraints or are concerned with disturbing the rest of the system.
The C127TC incorporates a hinge design that utilizes one 5/64" (2.0 mm) locking cap screw. The hinged clamp supplies the mounting force needed to secure the component in place. The C127TC can be mounted directly to any of our posts using the #8 (M4) counterbore on the bottom of the clamp.
Alternatively, the C128CC is a two piece design that utilizes two captive 5/64" (2.0 mm) cap screws to connect the two pieces. A 5/64" (2.0 mm) locking setscrew is included to provide the mounting force needed to secure the component in place. Two #4 counterbores, spaced 30 mm apart, on the front of the clamp are included to attach the C128CC directly to any 30 mm cage component with 4-40 mounting taps. This allows for the creation of an enclosed optical path between two 30 mm cage accessories using our aluminum lens tube covers, as shown in the photo to the right and above. The two piece design allows the cover to be easily removed to verify or correct alignment issues. Two 4-40 cap screws with a 5/64" (2.0 mm) hex are included to mount the clamp. The C128CC is also available in a pack of four, item # C128CC-P4.
