High Reflective Coatings
Dielectric High Reflective Coatings provide high reflectance over a broad
bandwidth, ideal for a tunable laser or in white light applications.
Metallic High Reflective Coatings provide low peak reflectance, mechanical
durability and high damage threshold.
Partial Reflective Coatings
Narrow Band Provide 50% reflection and transmission at an angle of 45 degree
incidence for a single wavelength. Transmission/Reflection ratio is 20/80.
Broad Band provide 50% reflection and transmission over a wide bandwidth.
Single Layer MgF2, applied to materials with refractive indices from 1.45 to
2.4, is the most popular AR coating for visible spectrum. Multilayer
coating is used to provide low reflectance with in a narrow durable
wavelength band for most laser applications. Minimum reflection can be less
than 0.1%. Broadband multilayer coating has excellent performance over a
broad range of spectrum. Coating performance is sensitive to angle of
incidence. Dual wavelength Band Low reflectance at two widely spaced
wavelengths, such as Nd:YAG Laser(1064nm) and its SHG(532nm).
