Ref0013

Aluminium coating for high temperature operation reflectors

The Ref0013 coating is an aluminium based high relfective coating combined with a protective ceramic top coating, which has shown excellent properties in the industry of stage and architectural lighting. Metal films are widely used for reflector surfaces.

The aluminium layer provides high reflection across the visible spectrum while the added transparent ceramic top layer adds outstanding performance in reflective capabilities at elevated temperatures. While silver can be used when corrosion is not a problem, aluminium can be used as both front-surface or back-surface reflector. Aluminium based reflector-coatings are often over coating with a protective polymer film.

The coating itself is manufactured by a sputtering PVD-process and optical properties are measured and controlled by advanced in-house FTIR equipment.

  • High reflection (+85%) across the visible spectrum
  • Continuous operation at 200°C (392°F) reflector temperature
  • Capability to withstand environmental impact from theatrical fog (artificial smoke)
  • Very good adhesion can be obtained with metallic reflector substrates
