Medium Extinction Broadband Polarizing Cube Beamsplitters
Medium Extinction Broadband Polarizing Cube Beamsplitters
Product name : Medium Extinction Broadband Polarizing Cube Beamsplitters
Description :
These polarizing cube beamsplitters provide a high degree of polarization over a broad visible spectral range. They are made by cementing the prisms together making them unsuitable for high power use. They use BK7 prisms and provide a medium extinction ratio of 100:1.
