Products

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. 


Features:

●Identical path lengths for both the reflected and the    transmitted beams;

●The transmitted beam is neither displaced nor deflected.
