Kinematic Center Mirror Mount / MHI

The Kinematic Center Mount is designed to allow the mirror to be loaded from the rear, keeping the reflective front surface centered above the mounting hole.

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 alighnment pin holes to accurately place mount in OEM instruments (φ3H7 except MHI-12.7, which is φ2H7).
