Ø50.8 mm Stainless Steel Adjustable Optical Mount MH3S-2
JCOPTIX Ø50.8 mm stainless-steel optical mounts suit demanding long-term stability. Heat-treated stainless bodies and fine bead blasting followed by coating provide stability, wear resistance, and corrosion resistance. Return-spring hooks are integral with front/rear plates. Fine M6 × 0.25 adjusters have small assembly clearance and low drift. Hardened stainless balls contacting sapphire pads provide smooth, wear-resistant adjustment. Two optic-mounting methods are offered for JCOPTIX Ø50.8 mm mounts: flexure springs with M4 set screws provide strong clamping and beam-pointing stability with easy installation; two retaining rings secure thinner optics and connect matching SM-threaded components. Two rear M4 countersunk holes mount posts. Upgraded Ø50.8 mm high-stability stainless mounts, 3 adjusters. Models: MH3S-2, MH3S-2H, MH3S-2T. 3 M6 × 0.25 adjusters; bead-blasted/coated for wear/corrosion resistance; ±3° angle and 6.0 mm Z travel; flexure spring or two-ring fixation. These JCOPTIX Ø50.8 mm mounts provide long-term stability, finely blasted/coated surfaces, and integrated spring hooks. Three M6 × 0.25 adjusters provide ±3° pitch/yaw at 0.27°/turn and up to 6.0 mm Z travel. MH3S-2 uses a flexure spring and M4 set screw accepting a 2.0 mm key to hold optics at least 1.0 mm thick. MH3S-2T has an SM2 aperture and two SM2 rings for optics up to 6 mm thick. Both have two rear M4 countersunk post holes; each includes two M4 socket-head cap screws and a 2.0 mm key. Upgraded Ø50.8 mm high-stability stainless mounts, 2 adjusters.

Both have two rear M4 countersunk post holes; each includes two M4 socket-head cap screws and a 2.0 mm key. Nonmagnetic Ø50.8 mm high-stability stainless mount, 2 adjusters. Model: MHS-2NM. Weakly magnetic materials throughout; ±3° angle; sapphire pads for smooth, wear-resistant adjustment; flexure spring or two-ring optic fixation. This JCOPTIX nonmagnetic Ø50.8 mm mount suits long-term stability and resistance to magnetization. Fine blasting/coating enhances wear, corrosion, and magnetization resistance. Return springs and adjusters are stainless steel. Ceramic tip balls reduce magnetic interference and contact sapphire pads smoothly. Two M6 × 0.25 adjusters provide ±3° pitch/yaw at 0.27°/turn. MHS-2NM uses a flexure spring and M4 set screw accepting a 2.0 mm key to hold optics at least 1.0 mm thick.

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.

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.
