ULTIMA Mirror Mounts used offer unsurpassed functionality. Thick front and rear plates and optimized, stiff springs improve the long-term stability and provide greater protection against vibrations. Hard carbide pads enable smooth, repeatable motion. This optical mount includes two 100 TPI non-locking actuators with knob providing ±7° of tip/tilt adjustment.

BSD periscope is built with 1 in. diameter solid stainless steel pedestail and post. If a taller beam steerer is required, simply attach a PS series extension post on top.

The actuators can be quickly changed to accommodate a broad selection of adjustment screws, micrometers, and motorized actuators. See compatible actuators in Accessories section below. 

The 45-degree mirror holders used on the BSD-2A periscope are easily removable allowing other ULTIMA series optic adaptors to be used in their place.
