VIS / NIR 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.
