Highly Stable Precision L-shaped Optical Mounts are designed on the basis of two angular adjustment mounts, and are made of steel with black chemical finishing. Flat spring of a special form is used in these mounts to provide pre-loading against the tips of two precise driving screws for elimination of backlash and ensure the absence of the roll coordinate. A special L-shaped design of the Mounts provides for maximum clear aperture.

Mounts have two M10x1 threaded holes for mounting of the actuators. This allows to use many different driving screws with these mounts. M6 tapped holes on the sides provide a wide variety of mounting configurations, either horizontal or vertical. The mounts can be fastened on any mounting post on its M6 tip. Additionally, mount 840-0040 has a hole on its back and can be mounted in horizontal position to be used as a tilt platform.

To enhance stability: the platform is preloaded by three special spring blocks; actuators push against hardened steel seats.The mounts have M6 mounting holes. Mount 840-0050 also has Ø42 mm clear aperture.

Material: black anodized aluminium (default), black finished steel (on request).

The codes for steel mounts are: 840-0040-S, 840-0050-S. The stage may be fitted with 2 or 3 screws. An option with 2 driving screws has a ball Ø8 as a third base-point. The stage comes with 870-0030 screw as a standard. If you order the stage with alternative screws, please specify this in order by appending the screw code name to the stage code.
