Cube Beam Splitter, FOCtek

12.7mm, 50R/50T Cube Beamsplitter, k9, 1500-1610nm, FOCtek



In stock

Cube beamsplitters are constructed by cementing two precision right angle prism together with appropriate interference coating on the hypotenuse surface. The absorption loss to the coating is minimal transmission and reflection approach 50% (average) though output is partially polarized. If polarization sensitivity is critical, FOCtek's Polarization Cube Beamsplitters or Non-polarization Cube Beamsplitters maybe the right choice for you.
