AR COATINGS 

Single-layer or multilayer coatings (V-coating, W-coating) can be applied to the surfaces of optical elements to reduce reflection and to improve transmittance. A coating with appropriate materials and layer configuration is deposited on a substrate material specified by the customer, with specified transmittance and a specified wavelength region. 

Substrates: Glass, quartz, sapphire, ruby, YAG, silicon, germanium, zinc selenide, zinc sulphide, and other optical crystals.

Wavelength Range: 193 µm to 10.6 µm.

Typical spectral characteristics

AR coating for decreasing less than 0.2% of reflectance at tip end of fibre. Free designs with single and multi-wavelength can be offered because coating is possible at low temperature.
