Committed to the Future, Fulfilling the Promise of Excellence

Specialty Mirrors

Mirrors have been used extensively, glass or metals are commonly used as substrate, followed by precision grinding and polishing of the surface to achieve the optical-grade flatness, parallelism, roughness, regularity, than applying metallic coating or multilayer dielectric coating on surface of the substrate. Control Optics provides various customized mirrors according to customers’ requirements.

Control Optics has developed mass production for customized products in recent years:

Parabolic-reflector for astronomical telescope, zero expansion glass with 1/20λ high-precision flat mirrors, large size cold mirrors, large size metallic coating mirrors, and aspheric reflector, etc.
