1.5 in. Magnetic Base Optical Pedestals

SR-Z Series 1.5 in. (38.1 mm) diameter solid stainless steel optical pedestals with magnetic bases allow faster, easier, and more accurate alignment of optical systems compared to traditional pedestals. The machined-in pedestal base provides the most stable and rigid means of mounting components to an optical table, while the magnet hold ensures secure positioning while clamping the base to the surface. Optical mounts can be directly attached to these pedestals without the need for a separate adapter.

Features

Designed for Maximum Stability

Constructed from solid stainless steel, the SR Optical Support Rods are designed for maximum stability by integrating multiple features into a single part. Rather than having several separate adaptors, these support rods have a machined-in pedestal base for use with SR-F clamping forks and multiple machined-in mounting holes.

Magnetic, Machined-in Pedestal Base

This unique mounting system provides the most stable and rigid means of mounting components to an optical table. Machined-in pedestals eliminate the need for an extra attachment before mounting to an optical table or breadboard, with clamping forks. Magnets located in the bases of the rods/posts hold them in place temporarily to facilitate ease of mounting and system alignment.

Two Types of Mounting Holes on Top

The rods have a center ¼-20 (M6) threaded mounting hole, as well as two additional 8-32 (M4) mounting holes, which are in line with the center hole, and are offset by ½ in. (12.7 mm). Using these two additional mounting holes, mirror mounts can be directly attached to the rod without the need for a separate adaptor.

Accessories for Customizable Heights and Architectures

A host of accessories for the rods are available, such as SR-E threaded extension posts and SR-S spacers, SR-Q mounting cubes, SR-SC sliding clamps and SR-ADP mounting adaptors, to allow mounting optics at non-standard heights and versatile architectures.

Compatible with Aegis Qube™ Beam Routing System

SR series pedestals can be used for the steel Aegis Qube™ Beam Routing System via adapter Q-XE-RA-1, which is made to attach to Q-OC-1 cubic enclosure to provide modular and versatile means for routing, shielding, and enclosing laser or similar light beams above an optical table.
