Laser Line Polarizing Cube Beamsplitters (PB)
Wavelength specific
- Low power – cemented
These polarizing cube beamsplitters are intended for use with lasers operating at a single wavelength. They are coated to achieve a high extinction ratio between the s and p components. They are manufactured from BK7 prisms which are cemented together and provides an extinction ratio of 1000: 1.
