Features

Versatile High stable Mounts for Optical Components

PS Series 1 in. (25.4 mm) diameter optical pedestals are made from precision ground stainless steel to maintain long-term optical system alignment. Pedestal bases, machined directly into the posts, provide versatile positioning and mounting directly to optical tables and breadboards using clamping forks. Each optical pedestal is marked with index grooves spaced by 1 in. (25.4 mm) for quick height reference. Both ends of the pedestals have a centered 8-32 (M4) threaded hole for mounting components and accessories, as well as stacking pedestals together.

Custom Heights with Spacers and Extensions

PS Series optical pedestals can be stacked with PS-E extension posts and PS spacers to provide custom mounting heights. Extension posts feature threaded hole in both ends and a variety of heights from 0.5 in. (12.7 mm) to 4 in. (101.6 mm). Spacers with centered clearance hole are available from 0.031 in. (0.79 mm) to 0.25 in. (6.35 mm) in height. 

Wide Variety of Pedestal Accessories

Post clamps provide the option of securing an optical mount at any position and any angle to a post and feature the 8-32 thread common to the series. 45-degree mirror mount adapters allow a mirror mount to be post-pointed at a fixed 45° pitch angle, which is ideal for periscope applications. For versatile, high-stability mounting in multiple dimensions, our modular construction cubes are the best choice. And to facilitate flexible mounting and stacking of optical posts, 8-32 (M4) to ¼-20 (M6) thread adapters are available. 

PS-45 Series Pedestal Adaptors

Cross-Drilled Hole for Easy Tightening and Loosening

These pedestals feature a 0.234 in. (5.9 mm) diameter cross-drilled hole. By inserting a 3/16 in. (5 mm) hex wrench (or similar tool) into this hole, it can be used to easily attach or detach an extension post or optical mount on its top.

Periscope Beam Steering Applications

A beam steerer can be built by attaching an extension post to a pedestal post and adding sliding clamps with mirror mounts.

Stable Low Beam Height Platforms

Pedestal posts allow for a low beam height, maintaining high stability and long-term alignment. Clamping forks let you locate them anywhere on an optical table.

LaserClean™ Low VOC Versions Available

Many laser-based applications require extra care to reduce volatile organic compounds (VOC) and ensure added cleanliness. VOCs and other contaminates can deposit on to optical surfaces causing degradation in output power, beam quality, and wavelength. Newport now offers certain Opto-Mechanical components that are specially prepared with clear anodize, nickel plating or stainless steel materials, special lubrication and vacuum-level cleaning. Products are packaged in Class 1000 (ISO 6) cleanroom grade bagging material and then double-bagged for further cleanliness precautions. We call these products, LaserClean™ and designate them with a -LC suffix. For more information please visit LaserClean Low VOC Optical Components Page.
