◦When this mount is rotated 45 degrees on an optical bench, the center of mirror will stay at the optical axis.
◦Cutouts and bevels allow these to be used as beamsplitter holders and not interfere with the transmitted beam.
◦Building the mirror frame into the support of the holder keeps the mount thin with a small footprint.
◦The small footprint allows more room to access the adjusters compared to regular kinematic mirror holders.
◦Includes alignment pin holes to accurately place mount in OEM instruments(φ3H7 except MHI-12.7, which is φ2H7).

Guide ▶Vertical control gimbal mirror and beamsplitter holders (BSHL) where the rotation of the fine adjustment matches the mirror center are also available.
WEB Reference Catalog Code/W4021
▶Can be mounted using an M4 low head screw to secure them from the top or an M6 threaded post from the bottom. (MHI-12.7 can be mounted with an M3 low head screw from the top and M4 threaded post from the bottom.)
Attention ▶MHI-12.7 limits the tilt and rotation to be ±1° and ±2° respectively, even when a low and small head hexagon socket head cap screw is used.
▶When securing a mirror with a low head hexagon socket head cap screw, a hex wrench may interfere with the mirror. Please retract the mirror by turning the rotation and tilt adjustment screws before tightening the low head hexagon socket head cap screw.
▶When securing a mirror on a baseplate with a M4 low head hexagon socket head cap screw, there will be ±1mm clearance.
