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.

The CM-3B3C with M3 set-screw head can be used to secure optical components with a diameter of Ø25.4 mm and a thickness range of 3 mm to 8 mm. The mount base features an M4 threaded hole, allowing connection to a Ø12.7 mm stainless steel optical post. It can be paired with the 30 mm coaxial cube CM-3 for mounting 30 mm coaxial systems while also protecting the optical components.

The CM-3R is commonly used for direct mounting of LBTEK standard-sized rectangular dichroic mirrors measuring 36 mm × 25 mm. Its maximum mounting dimensions are 42 mm × 30 mm with a maximum thickness of 3 mm. The cube structure effectively protects optical components. The base features an M4 threaded hole for connection with Ø12.7 mm stainless steel optical posts. The M3 threaded holes on all four sides of the cube are compatible with 30 mm coaxial systems, while the four SM1 threaded holes can be used to integrate lens tube series. Additionally, utilizing the pin holes on all four faces, multiple cubes can be interconnected through coaxial cube connectors (CMC).

The CM-3B4C is designed for direct installation of LBTEK standard-sized rectangular dichroic mirrors measuring 36 mm × 25 mm, with a maximum mounting size of 42 mm × 30 mm and a maximum thickness of 3 mm. The optical component is secured/released through spring compression and a single screw that simultaneously tightens or loosens the spring. The mount base features an M4 threaded hole, allowing connection to a Ø12.7 mm stainless steel optical post. It can be paired with a 30 mm coaxial cube cover for installing 30 mm coaxial systems while also protecting the optical components.
