Periscope Assembly Designed for Use with Ø1" (Ø25.4 mm) Optics
Minimum Optic Thickness: 0.13" (3.3 mm)
Complete Assembly (RS99) Redirects and Changes the Height of a Beam Within an Optical System
Components Sold Separately for Wider Range of Height Adjustment

The RS99 Periscope Assembly (pictured right) provides a convenient way to redirect and change the elevation of a beam within an optical system. The system consists of a pair of 45° mirror mounts 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.

Response from Buki at Thorlabs to mstocker: Thank you for your feedback. The RS99 includes a 6" (150mm) pillar post, so the height change of the beam would be less than 150mm because the mounted mirrors will not be placed at the very edge of the post. The post, RS6, is stackable, so you can connect two of them with a 1/4"-20 set screw, or with the AE8E25E screw adapter that ships with each pillar post. Please use the link below to get more information about the pillar post. We have a variety of lengths that will help you achieve the height change you want for your beam. Please contact TechSupport@thorlabs.com if you have any questions. http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=241&pn=RS6#2006

I need to reflect a beam 90 degrees (parallel to the laser table) and change the height by ~ 1.5 cm. With the 45 degree mounts for RS99, will it be possible to do this? If not, is there another option?

Response from Laurie at Thorlabs to xdcui: Thank you for your feedback. The imperial version (RS99) has an 8-32 thread and the metric version (RS99/M) has an M4 thread. We offer a screw adapter from either of these standards to the M6 standard. To go from M4 to M6, I suggest item# AP6M4M, and to go grom 8-32 to M6, we have AP6M8E.

I notice that the mounting hole on the top of the rod is M4 (RS99). While all your 1" extension rods have the mounting tap of M6. How to make them connected?
