Large Diameter Periscope Mounts

Large diameter periscope mounts fit securely with the Model 75 damped support base and offer precision steering of beams up to 1.5 in. (38.1 mm) in diameter. Height is adjusted easily and precisely by hand for both mounts and course/fine adjustments knobs with an aziumthal angle sensitivity of 8 arc seconds. Mirrors and 1.5-in. diameter rods are sold separately.

Flat 45 degree mounting surface accepts a variety mirror shapes
76 to 270 mm optical axis height adjustment (req. model 70 optical rod)
Rack-and pinion gear mechanism for precise manual height adjustment
Coarse-fine azimuth angle control for accurate beam steering
Unmatched stability when used with our patented damped rods
Smooth, chatter-free vertical height adjustment

Features

Compatible With Large Mirrors

These periscope beam steering mounts offer precise adjustment to the height and direction of laser beams up to 1.50 in. diameter. They are compatible with 1.84 X 2.60 in. elliptical mirrors and large 1.5 in. diameter mirrors to provide a wider adjustment range than standard or general-purpose periscope assemblies. The mirrors are bonded to the mount using double sided tape.

Course/Fine Azimuthal Adjustment for Beam Steering

These mounts have both coarse and fine azimuth adjustments for precise beam steering. The lower mirror is pivoted easily by hand with an integrated knurled knob, while the upper mount has both a knurled knob for coarse azimuth positioning over 360° and high-resolution adjustment screws or micrometers for precise beam pointing in azimuth and elevation.

Precise Manual Height Adjustment

Used with our patented Model 75 Damped Rod, the 670-RCT is fully adjustable in height with a hand turned knob that smoothly moves the mount horizontally. The rigid and sophisticated construction provides excellent stability with 100% faster vibration decay for critical applications.
