Pitch, Yaw, and Rotation
This animation shows how the periscope assembly is used.
Thorlabs' Periscope Assembly provides a convenient way to redirect and change the elevation of a beam within an optical system. As seen in the animation, the system consists of a pair of 45° Ø1" mirror mounts (optics sold separately) with lockable adjustment knobs to provide 360° of rotation of the incoming light.
The top unit, which can be purchased separately below, provides pitch, yaw, and rotation control. It features 360° of continuous rotation as well as ±4° tip and tilt with an adjustment per revolution of 8 mrad/rev. This unit can hold Ø1" optics that are at least 0.13" (3.3 mm) thick.
The bottom unit, which can also be purchased separately below, provides a right angle mirror mount for Ø1" optics as well as a clear aperture for beam sampling. This unit is mounted to the Ø1" post using a 360° continuous rotation pillar post clamp.

Thorlabs' Smart Pack Initiative is aimed at waste minimization while still maintaining adequate protection for our products. By eliminating any unnecessary packaging, implementing packaging design changes, and utilizing eco-friendly packaging materials for our customers when possible, this initiative seeks to improve the environmental impact of our product packaging. Products listed above are now shipped in re-engineered packaging that minimizes the weight and the use of non-recyclable materials.b As we move through our product line, we will indicate re-engineered packages with our Smart Pack logo.
The RS99(/M) Periscope Assembly includes the top and bottom units, Ø1" post, and clamping fork. The top unit provides pitch/yaw adjustment, which can be used to compensate for angular deviations of the input beam relative to the Ø1" (Ø25.4 mm) optic (not included). When used with standard 6 mm thick mirrors (not included), the center points of the mirrors can be positioned with a separation between them of 1.0" and 2.7" (RS99) or 25.4 mm and 65.5 mm (RS99/M). The included 6" tall post [RS6 (RS150/M)] can be extended using Ø1" Pillar Post Extensions and the included thread adapter.
The RS99T(/M) Top Unit is offered for customers who want to create their own periscope assembly on an arbitrary length Ø1" Pillar Post or post assembly. This assembly includes the kinematic post clamp with ±4º tip and tilt in addition to 360° continuous manual adjustment. The bottom unit, post, base, and clamping fork packaged with the RS99 periscope assembly featured above are not included with the RS99T.
The RS99B(/M) Bottom Unit is a right angled mirror mount for use in a periscope assembly on an arbitrary length Ø1" Pillar Post or post assembly. This unit clamps to the post and offers 360° of continuous rotation without tip/tilt adjustment. The top unit, post, base, and clamping fork packaged with the RS99 periscope assembly featured above are not included with the RS99B.
