Dielectric mirror GCC-1021 series

squareBK7aluminium

This design provides better performance than the protected aluminum coating with an average of about 92% reflection in the visible spectrum. The coating incorporates the use of a dielectric stack on the aluminum, which provides better resistance to abrasion than the raw metal. •Diameter Tolerance： +0.0/-0.15 •Thickness： ±0.1 •Parallelism： 99.5% for 45˚ angle of incidence Rave>92% throughout VIS
