Lens Mount Selection Guide

Optical Lens Mounts are used to securely locate a lens in an optical assembly or during optics research. There are versions for standard size lenses or objectives, and variable sized versions that accommodate a range of lens diameters. They are available for fixed position applications or with precision multi-axis adjustments.
