The manufacturing capabilities of extensive lens use all types of materials and processes. We adopt the best process technology to produce the required specs. This allows us to reach the required optical performance desired from a given material. Our best practices have been developed from years-long experience to reach timely and efficient production.
SGOPTICS has extensive lens manufacturing capabilities using all types of optical glasses, fused silica and crystalline materials including CaF2, Ge, MgF2, Si, ZnSe, ZnS and Amtir. We adopt the best process technology from spindle polishers, CNC polishers, magneto rheological finishing or a combination so as to produce the required specs – some subtle such as low spatial frequency, some more distinctly beneficial such as low surface roughness – to reach the required optical performance from a given material.
Tight centering, truncation, high included angle or long radius – we use best practices developed from years-long experience to reach timely and efficient production. We have a huge library of test plates and a lot of current model Zygo interferometers, all with complete reference spheres for maximum precision in surface measurement.
