Flat plates HR Mirrors

Every surface reflects light. The reflected light is both diffuse and regular (or specular) and sometimes comes both from the surface and the bulk material. The reflectance of a surface with a dielectric coating depends on the optical properties of both the substrate and the coating.

Coating can be designed for very high reflectance or as partial reflector. The useful wavelenght range of any dielectic reflector is limited.



Diameter Tolerence: +0mm - 0.2mm
Parallism: < 1 arc minute
Clear Aperture: > 80%
Thickness Tolerence: +/- 0.2mm
Wavefront Distortion: ^/10@632.8 mm per 25 mm
Surface Quality: 20/10 scratch and dig
Bevel: 0.25mm x 45 degree


BKY grade A optical glass n = 1.5183 +/- 0.0005 (@546.1mm)
High purity uv grade fused silica n = 1.4608 +/- 0.0005 (@546.1mm)
