Kinematic Mirror / Beamsplitter Mounts 840-0056 are used for precise angular and linear alignment of optical elements. We provide two types of kinematic mirror/beamsplitter mounts: for round optical elements (840-0056-11; 840-0056-12; 840-0056-13) and for square optical elements (840-0056-21; 840-0056-22; 840-0056-23).

• 1", 2", 3" optics mounts
• Tilt range 9° (about two axes)
• Travel range 4 mm
• Sensitivity 3 arcsec or 1µm
• Mounting on either of 2 sides
• Made of black anodized aluminium
• Motorized version 940-0060 available

840-0056 has a resting flange to stop the optics. One fixing screw (two in “square” mounts) secures the optics against hard rests, which make 2 contact points. To prevent damage to the optics, the tip of the fixing screw is made of plastic.

Square mounts 840-0056-20 additionally have 4 fixing screws for thin optics. They have conic tips to work as wedges to clutch a thin plate of optics to the resting flange. For thick optics square mounts have 2 screws rather than one.

A platform is preloaded by two strong coil springs, ensuring tight kinematic fit. A thick base adds to stability. This allowed us to eliminate part of the mount, keeping clear one edge of the optics.

As standard, mounts come with screws 870-0080.  You may order the mounts with 2 or 3 adjustment screws. The prices are given of kinematic mirror/beamsplitter mounts with 3 driving screws.
