Broad Band AR coating for the visible and IR range
This broad band, dielectric, AR coating designed to minimize reflectance over broad wavelength range 430-900nm and substrates with refraction index in the range 1.51-1.55.
The coating can be extended to the higher refractive indexes of the substrates.
The coating can be applied to variety of optical materials transparent in the range 400-2000nm.
Coating characteristics: for the substrates with n=1.51-1.55
- Average Reflectance: less than 0.8% per surface in the range 450-900nm.
- Maximum Reflectance: less than 1.0% per surface in the range 450-880nm
- Average Transmittance (per surface): greater than 99.0% in the range 450-900nm
Environmental and durability:
- The coating meets durability requirements of MIL-C-48497 including moderate abrasion as per Para 188.8.131.52.
