Partial Reflection (PAR)
400
nm ≤ λ ≤ 2.0 µm
Partial Reflection coatings are widely used for beamsplitting, beam
sampling and laser output coupling. They divide an incident, monochromatic
beam into reflected and transmitted components with the specified intensity
ratio. Coatings for high power wavelengths use special materials that
are able to withstand higher power than standard partial reflection
coatings. These all dielectric coatings are sensitive to polarization,
wavelength and angle of incidence.
