IR Partial Reflection (PAR)
2.0 µm ≤ λ ≤ 20.0 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. These all dielectric coatings are sensitive to polarization, wavelength and angle of incidence. They are durable and highly resistant to laser damage.
