High-precision Mirror


The Company is quite good at making large-aperture high-precision optical flats, spherical surfaces, aspheric surfaces, and even free-form surfaces; with the Company's full set of production lines and sophisticated inspection methods and equipment, the roughness of the processed optical mirror surface can reach 0.4 nm, the max. processing diameter being up to 1.6 m, and the surface accuracy RMS being superior to λ/100. The accuracy of the finished large-aperture optical mirror surface reaches the first-class level in China.
