UVグレード石英ガラス平面基板
（高面精度）

Ideal substrates for planar optical components, such as plane mirrors, filters, or beamsplitter plates
Ideal for use as windows in optical systems
Superior quality plates with high flatness of λ/10 on one surface (marked)
4 diamond polishing: better than 1 nm rms
Surfaces uncoated
Our plane plates are also available with the following coatings:
VIS range (ARB2: R < 0.5 % per surface, AOI = 0°, λ = 450 - 700 nm).
NIR range (ARB2: R < 0.5 % per surface, AOI = 0°, λ = 725 - 1050 nm).
Nd:YAG fundamental (ARHS: R < 0.2 % per surface, AOI = 0°, center wavelength 1064 nm)
Reflective aluminum coating (RAL: for λ = 400 nm - 12 µm, damage threshold > 200 mJ / cm²)
Front surface mirror silver coating (RAGV: for λ = 500 nm - 12 µm, damage threshold > 200 mJ / cm²)
