Our manufacture

We have State of the Art coating facilities, operated by experienced operators in the ISO 7 clean room. Our IAD vaporization plants permits maximum flexibility. The result is compact coating with high stability. The substrate is cleaned in automated ultrasonic systems.

We inspect all coatings using spectrophotometers and standardized environmental norms (MIL/ISO standards). We have the LIDT characterization carried out by an external, independent institute. This is how we guarantee quality and the specifications that have been agreed with the customer.

Metrology

  • Spectrophotometer for reflectance & transmittance measurements
  • Perkin-Elmer Lambda 900 (measuring range 185 - 3300 nm)
  • Perkin-Elmer Lambda 950 (measuring range 185 - 3300 nm)
  • Essent Optics PhotonRT (measuring range 185 - 1700 nm)
  • Eta-Arc for reflectance measurement 6° on curved surfaces (measuring range 400 - 800 nm)
  • Environmental and climatic tests according to ISO and MIL (temperature and humidity)
  • Various climatic chambers
  • Tempering oven (temperature up to 700°C)
  • Laser induced damage threshold (LIDT)

Cleanroom

  • Coating equipment, including testing and handling area is in an ISO 7 cleanroom (Class 10,000)
