Aspheric Mirrors

Bases of aspheric mirrors and parabolic mirrors can be made from various materials, normally using thicker materials such as optical glass, Pyrex, BOROFLOAT, fused silica, ZERODUR, CLEARCERAM™-Z or metallic materials as substrate, followed by precision grinding and polishing or metallic ultraprecision processing for optical-grade roughness, regularity achieving the best reflectivity by applying aluminum, sliver, metallic or multilayer dielectric coating on substrate.

Control Optics successfully developed the measuring method for parabolic surface in 1997, completing mass production of 1/10λ high-precision parabolic mirror, which has been applied in astronomical telescope.
