Product information "Anti-Reflection Coating"
Together with our supplier Vortex we provide broadband and V-style anti-reflection (AR) coating from 300 nm to 6000 nm. We offer AR coatings service on your optics with an unrivalled rapid turnaround or can also supply “make complete” AR-coated optics with substrates sourced through one of our trusted suppliers.
Our AR coatings can be customized to your application’s requirements – contact the AMS Technologies experts today to discuss your customized anti-reflection coating solution!
Broadband AR Coating
A number of standard broadband processes covering many spectral regions is available that can also be adjusted for your specific requirements, e.g. the coating’s properties can be moved to a number of different bands if required. Some examples of broadband AR coatings:
Broadband AR Coatings | ||
Optimized Wavelength | Substrate | Average Reflection Within Wavelength Band |
AR 400-700 nm | Glass | <0.5% |
AR 400-900 nm | Glass | <1.0% |
AR 400-1100 nm | Fused Silica | <1.0% |
AR 400-1700 nm | Sapphire | <3.5% |
AR 400-2500 nm | Sapphire | <8.0% |
V-Coating
As a special type of anti-reflective coating, V-coatings improve transmission in a very narrow wavelength range around the design wavelength. This type of coating is called a "V-coating" because the curve of the reflection over the wavelength resembles the letter "V", with a minimum at the design wavelength. Both single- and multiple-wavelength V-coat processes are available for laser and LED applications covering a range from 300 nm to 6000 nm, with maximum reflection of <0.25% per surface at the designated wavelength. Some examples of V-coatings:
