30 mm coaxial flat optical element mount CM-3C

The CM-3C can be used to mount optical components with a diameter of 25.4 mm and a thickness range of 3 mm to 8 mm. It features M3 set-screw fixation and a 45° mounting angle for optical components, with the mounting step aligned at 45° to the base for coaxial beam transmission in optical systems. The base includes an M4 threaded hole for connection to a Ø12.7 mm stainless steel optical post. The mount is equipped with M3 threaded holes on all sides, compatible with 30 mm coaxial systems, and SM1 threaded through-holes for standard SM1-threaded accessories. Note: Please use the dedicated hex key provided by LBTEK to tighten the four black hex socket head cap screws. Using other tools, especially ball-end hex keys, may strip the screw heads. When tightening, secure the internal components without excessive force. It is recommended to periodically replace the socket head cap screws, which are M2.5x6 in size.
