Single or Multilayer AR Optical Coatings
All our anti-reflection optical coatings can be centred at any wavelength between 350nm and 2500nm and have an excellent adhesion and abrasion resistance. They also withstand high humidity, salt spray, acids, etc. and have proven high damage thresholds when used in laser systems.
They can be applied to a variety of substrates ranging in size up to about 1.5m for single layer coatings and up to 0.4m dia for multi layers. (See Data Sheet 211 for details of anti-reflection coatings on Fibre optics).
The curves on the graphs below indicate measured performance of our anti-reflection coatings for a single glass surface with a refractive index of 1.52.
The applications for optical antireflection coatings in both military and civil equipment are too numerous to list. However, TMF has gathered much experience in different applications and would be pleased to discuss your particular requirements.
