The CM-R/S mounting brackets from LBTEK are designed for 360° manual rotation of optical components in a 30 mm coaxial system. The CM-R utilizes two included retaining rings to mount optical components with Ø25.4 mm diameter and a maximum thickness of 7.4 mm. The CM-S can accommodate optical components with Ø25.4 mm diameter and a minimum thickness of 4.7 mm, securing them via side set screws. Both CM-R/S models feature flexible clamping blocks and M3 locking screws, enabling quick installation of optical components without disassembling the coaxial rod. By loosening the M3 locking screws on both sides, the brackets can be rapidly snapped into or removed from the coaxial rod. The red knob on top can be rotated using either knurling or a 5 mm hex wrench, while the side M3 screw locks the rotation. The red knob includes 5° interval markings for angle indication.
