Narrowband Anti-Reflection (NAR)
400
nm ≤ λ ≤ 2.0 µm
Narrowband Anti-Reflection coatings, often referred to as "V"
coatings, reduce surface reflectance to less than 0.25% at the specified
center wavelength and normal incidence. "V" coatings are better
suited to laser applications than single-layer AR coatings. Coatings
for high power wavelengths use special materials that are able to withstand
higher power than standard narrowband antireflection coatings. These
all dielectric coatings are sensitive to polarization, wavelength and
angle of incidence.
