High Power Laser Polarizing Cube Beamsplitters (HPB)
Wavelength specific
- High power – optically contacted
These polarizing cube beamsplitters are intended for use with high power 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 either BK7 or UV Fused Silica prisms which are optically contacted and provides an extinction ratio of 200: 1.
