Optics Replication

June 1, 2010

OPCO Laboratory (Fitchburg, MA) provides a proprietary replication process that reproduces complex optics. It transfers the profile of a precision optical surface from a master, creating an exact duplicate on a variety of substrates. The process produces both ruled and holographic diffraction gratings, reflective and transmission holographic optical elements, an dual-wavelength gratings, as well as plano and conic sections. Substrate materials include glass, silicon carbide, ceramic, and metals such as beryllium, aluminum, titanium, and stainless steel. Additional mounting holes and other features such as tabs can be incorporated into a metal replica. Diffraction gratings are produced in sizes up to 110 × 110 mm with groove densities from 40g/mm to 3600 g/mm, with available wavelengths from the deep UV to the far IR.
