30 mm Coaxial Rotation Mount MCRM-1P
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.

Height- and Angle-Adjustable Coaxial Support Mount IMA-ADB Optical Mounts / Kinematic Mounts Jcoptix
Body Material: 6061-T6 Surface Treatment: Black Anodized Compatible Cage System: 30 mm Cage System
JCOPTIX height-/angle-adjustable cage supports hold multilayer systems, with independently adjustable layer heights and rotating support plates for angular adjustment. Modular designs use different rod lengths for height and add/remove IMA-ADB lift plates for layer count. After positioning, secure the base to the table/breadboard, lock rotation, then use setscrews/flexure screws to connect lift plates to supported rods/tubes and two vertical rods. Multiple-direction fixation provides stability, reliability, and flexibility. Adjustable supports for 30 mm systems. Models: IMA-ADB, IMA-ADB1, IMA-ADB2, IMA-ADB3. Simultaneous multilayer support. Multiple lift ranges. For 30 mm systems and SM1 tubes. Assemblies comprise long bases, rotating plates, lift plates, and vertical MCR rods. IMA-ADB is a separate lift plate for adding/removing layers. IMA-ADB1: height 35-62.6 mm; angle ±30°; two 76.2 mm MCR-3 rods and one IMA-ADB plate. IMA-ADB2: height 35-240 mm; angle ±30°; two 254 mm MCR-10 rods and two IMA-ADB plates. IMA-ADB3: height 35-291 mm; angle ±30°; two 304.8 mm MCR-12 rods and three IMA-ADB plates. After adjustment, two supplied M6 cap screws secure the base. M4 setscrews and M4 cap screws lock rotation. M4 setscrews, M4 rubber-tipped screws, and M2.5 cap screws connect lift plates to supported rods/tubes and two vertical rods, ensuring stable multidirectional fixation and system flexibility.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
