Fine-Pitch Adjustment Screws

OptoSigma Fine-Pitch Screw Adjusters are offered as a replacement or in place of our standard micrometers. The precision screws are turned from high grade stainless steel and are supplied with a matching brass nut designed to fit our stages and mirror mounts. They are lockable by means of a set screw on the nut using an Allen wrench. The M6.25 screws are designed to drive OptoSigma’s 40mm, 60mm, and 65mm stages. The M4-P0.25 screws are designed for use with the 25 mm stages.
