30 mm Coaxial Rotation Mount MCRM-1T
JCOPTIX 30 mm cage rotation mounts rotate angle-sensitive polarizers, waveplates, and other polarization optics. A central standard SM1 hole holds Ø25.4 mm optics. Continuous smooth, backlash-free 360° wheels have clear 2° divisions and numerical labels every 20°. Angled scale faces aid precise movement/repositioning. JCOPTIX 30 mm mounts come in basic and micrometer-fine-adjustment versions. Basic models rotate manually. Fine versions add vernier scales/micrometers: coarse resolution improves to 5′, with ±7° micrometer travel at 1.2′ resolution after coarse locking. Basic 30 mm cage rotation mounts. Models: MCRM-1T, MCRM-1. Ring or setscrew retention. Central standard SM1 hole for Ø25.4 mm optics. Bottom M4 hole. JCOPTIX basic 30 mm mounts have central SM1 holes for Ø25.4 mm optics. SM1 bore versions are threaded or smooth. Threaded models include a retaining ring; smooth models use a side M4 rubber-tipped screw and dual-line locating bore. Bottom M4 holes connect to 12.7 mm posts. 30 mm cage rotation mount with micrometer fine adjustment. Model: MCRM-1P. Lockable 360° coarse rotation. 2° main divisions, 10′ vernier resolution. After coarse locking: ±7° fine travel, 1.2′ resolution. Holds Ø25.4 mm optics up to 11 mm thick. JCOPTIX MCRM-1P accepts Ø1 inch (Ø25.4 mm) optics up to 11 mm thick in an SM1 threaded mount, secured by the supplied SM1RR ring. MCRM-1P rotates manually to any position and locks via a side setscrew using a 1.5 mm wrench; a backlash-free micrometer then fine-adjusts. MCRM-1P has 2° divisions and 10′ vernier resolution, with ±7° locked-coarse fine travel at 1.2′ resolution. MCRM-1P fits 30 mm systems or post-mounts through M4 holes.
