Coating of optical components

1. Antireflective film:

400-700nm ≤ 0.5% broadband ultra-low reflection, meeting the requirements of 0-45 degrees wide angle low reflection. Not only does it meet the requirements of flat glass, but it also has relatively uniform low reflectivity and stable reflectivity for large size (R ≤ 300mm) convex concave lenses. 1064nm laser single point penetration film T ≥ 99.8%.

2. High reflection film:

(1) Metal medium high reflectivity: Metal aluminum with medium high reflectivity can achieve stable reflectivity in specific wavebands, solving the defect of metal with different reflectivity at the same wavelength. Metal silver with medium high reflectivity can achieve a reflectivity of 98% in specific wavebands.                                                          (2) Medium high reflection film: 400-700nm, R ≥ 99%, incidence angle 0-45 degrees.
