Free-Space Rotation Mount MMRS-2T

JCOPTIX free-space rotation mounts provide smooth backlash-free 360° orientation of Ø12.7 mm, Ø25.4 mm, and Ø50.8 mm round optics, with screw locking. Protruding straight knurling eases adjustment. Clear 360° scales have marks every 2° and numbers every 20° for precision/repeatability. Bottom M4 threads attach posts. Alternatives include independently zeroable dials and dual independently rotating optics. SM-threaded free-space mounts, retaining-ring fixation. Models: MMR-05T, MMR-1T, MMR-2T. Accept Ø12.7 mm, Ø25.4 mm, Ø50.8 mm optics; central SM threads fit SM components; one retaining ring. JCOPTIX mounts smoothly rotate Ø12.7 mm, Ø25.4 mm, Ø50.8 mm optics through 360° without play and lock with top set screws. Place optics in the SM aperture and tighten the supplied SM ring with a spanner. Bottom M4 holes attach 12.7 mm posts. Smooth-bore free-space rotation mount, set-screw fixation. Model: MMR-1. Ø25.4 mm optics; smooth bore gives stable two-line contact; rubber-tip screw. It rotates Ø25.4 mm optics smoothly through 360° without play and locks at the top. An M4 rubber-tip side screw and two-line locating bore hold optics. Bottom M4 threads attach 12.7 mm posts. Precision-bearing rotation mount, retaining ring. Model: MMR-1TRS. Ø25.4 mm optics up to 12 mm thick; SM1 aperture for SM1 components; one ring; 2 precision bearings. Two bearings provide smooth motion. The SM1 internal aperture holds Ø25.4 mm optics up to 12 mm thick with an SM1RR ring. SM1 threads also accept SM1 tubes and other SM1 components. Knurled edges aid rotation; 360° laser marks have 2° divisions. A top screw accepting a 2 mm key locks rotation. Free-space mount with independently adjustable/zeroable dial. Model: DMR-1D. Ø25.4 mm optics up to 14 mm thick; independent dial rotation/zeroing; SM1 aperture for SM1 components; one ring. Two precision bearings provide smooth backlash-free 360° rotation with top locking. Unlike MMR-1(T), the dial rotates/zeros independently of the optic. Loosen dial-cover countersunk screws with the supplied 1.5 mm key, align the scale to the optic axis, then relock. The SM1 center accepts Ø25.4 mm optics up to 14 mm thick or SM1 components. Bottom M4 threads attach 12.7 mm posts. Dual free-space mounts for two Ø25.4 mm optics. Models: MMDR-1, MMDR-1A. Two Ø25.4 mm optics up to 6.4 mm thick; independent rotation; interchangeable magnetic quick-release rings; SM1 centers fit SM1 components. Two rings hold Ø25.4 mm optics simultaneously, minimum separation 7.6 mm. Both rotate independently/continuously through 360° with top locks. Nearby linear polarizers/waveplates form adjustable polarizers/attenuators without aligning two separate mount axes. Each ring has an SM1 aperture for optics up to 6.4 mm thick. Ring/base magnets permit quick removal and interchange between bases. Separate MMDR-1A rings allow rapid optic changes. Bottom M4 holes attach 12.7 mm posts. Dual free-space mounts for two Ø12.7 mm optics. Models: MMDR-05, MMDR-05B. Two Ø12.7 mm optics; independent rotation; feature list specifies SM1 centers fitting SM1 components. Two rings hold Ø12.7 mm optics with independent continuous 360° rotation and top locks. They suit nearby polarizers/waveplates without separate axis alignment. Two models for Ø12.7 mm optics are MMDR-05 and MMDR-05B. MMDR-05 uses magnetic removable/interchangeable rings. MMDR-05B has two internal lock rings and cannot be disassembled, suiting nonmagnetic environments. The body specifies SM05 centers for both, with bottom M4 holes for 12.7 mm posts. Thin SM-threaded free-space mounts, retaining-ring fixation. Models: MMRS-05T, MMRS-1T, MMRS-2T. Accept Ø12.7 mm, Ø25.4 mm, Ø50.8 mm optics; central SM threads fit SM components; one ring plus shoulder. These JCOPTIX mounts rotate Ø12.7 mm, Ø25.4 mm, Ø50.8 mm optics smoothly through 360° without play and lock at the top. Markings on sloped rotation surfaces improve readout. Insert optics into the SM aperture and tighten the supplied SM ring. Bottom M4 holes attach 12.7 mm posts. Thin high-precision rotation stage for free-space use.Model: DMRP-1TS. Continuous 360° rotation with vernier readout; ±5° micrometer adjustment; side M4 post holes; Ø25.4 mm optics up to 12.7 mm thick; SM1 tube/30 mm cage compatibility; 1 SM1RR ring included. JCOPTIX thin stages precisely orient optics, with continuous 360° coarse and ±5° fine rotation selected by a side thumbscrew. Unlocked, the top rotates manually through 360°, with 1° marks and 5-arcmin minimum vernier reading. Tightening locks coarse rotation and permits backlash-free ±5° fine adjustment. Each 1 micrometer turn rotates the stage 1°; 1 turn has 50 divisions, each 0.02°. At only 20 mm thick, the compact stage particularly suits post-supported free-space optics. Two bottom M6 countersinks also allow horizontal table mounting: 1. Choose position and start two M6 screws in the corresponding holes. 2. Adjust screw depth, then slide the stage horizontally so both M6 screws enter its two bottom M6 countersinks. 3. Rotate the top until its notch aligns with the M6 screw sockets and tighten at an angle with a ball-end key.
