IR Non-Polarizing Plate Beamsplitter (NPP)
2.0 µm ≤ λ ≤ 20.0 µm
Non-Polarizing Plate Beamsplitter coatings divide an incident, monochromatic beam into reflected and transmitted components with the specified intensity ratio. They are designed for applications in which it is necessary to maintain the polarization characteristics of the incident beam. These all dielectric coatings are sensitive to wavelength and angle of incidence. They are durable and highly resistant to laser damage.
