Laser Line Non-Polarizing Cube Beamsplitters (NPB)
- Beamsplitter for single laser lines
- AR coating on four faces
- Low power applications
These non-polarizing cube beamsplitters are coated so that the s and p components coincide in reflectance at the wavelength of interest. This means that they will not change the state of polarization of the incident beam. They are anti-reflection coated on the four external faces. These are not intended for high power use due to the cement between the two prisms.
