OptoSigma manufactures the best quality substrates from the raw material purchased from the main glass suppliers. These substrates are then polished and antireflection coating is applied for different wavelength ranges. Ultra polishing to achieve low scattering surfaces or high flatness surfaces is also part of our capabilities. Antireflection coatings can be applied, as needed, for different wavelength ranges.
