Translating Optical Post, 0.5 in. Diameter, 8-32 & 1/4-20

The BTP2.0 0.5 in. diameter translating optical post is designed for faster, easier, and more precious height adjustment of optical components mounted on top. It provides highly stable and versatile mounting of optics, featuring a solid stainless-steel construction and an 8-32 threaded hole at the top and a 1/4-20 threaded hole at the bottom. This self-translating post allows accurate up and down movements of the optical component by rotating the adjustment collar easily done by one hand. The upper body of the post doesn't rotate when translated. When desired optical height is achieved, the integrated lock ring can lock the post in place, preventing unintended adjustment of the post.
