-
- Ideal substrates for planar optical components, such as plane mirrors, filters, or beamsplitter plates
- Ideal for use as windows in optical systems
- High flatness of λ/10 on one surface (marked)
- Grade P4 polishing one side (grade P3 on backside)
- 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)
