Non-Polarizers » Cube Beamsplitter (UV/VIS/NIR)


400 nm ≤ λ < 2.0 µm

Non-Polarizing Cube Beamsplitter coatings are deposited between two right angle prisms that are permanently cemented together. They divide an incident, unpolarized, monochromatic beam into reflected and transmitted components with the specified intensity ratio.

These coatings are designed for applications in which it is necessary to maintain the polarization characteristics of the incident beam.
