Windows & Substrates


Windows & substrates of the highest precision  

Substrates are components (plano-plano parallel polished components, lenses, prisms, filters, etc.) made of different materials that serve as the base to be coated to produce products like beamsplitters, mirrors, and windows, for example.

Windows are transparent, mostly plano-plano parallel polished and/or coated components that are used in optical systems to achieve highly-efficient, distortion-free light and perfect image transmission.

Examples of Products:
  • Plano parallel windows
  • Protective windows
  • Laser line windows that feature an antireflective coating
  • Optical flats
  • Substrates for microlithography
  • Brewster or elliptical windows
