Lens Assemblies

Lens Assemblies :

Welch Mechanical Designs is an industry leader in the design and manufacture of custom lens barrels. We have extensive experience working with anything from simple aluminum barrels holding glass optics to exotic designs combining high and low thermal expansion material to compensate for the thermal growth of the bulk lens materials as well as dN/dT, the thermo-optic coefficient.

We manufacture lens barrels with focus adjustment, fiber optic coupling interfaces, and Focal Plane Array focus adjustment features. We have also manufactured many small polymer lenses including gradient index materials for R&D projects. Many of these diamond turned crystalline and polymer lenses incorporate mounting features into the optics that are impossible with traditional polished optics.
