Non-polarizing beamsplitter cube are constructed by cemented two right angle prisms. 

► The hypotenuse of one prism is coated with hybrid metal dielectric coating, which exhibits moderate absorption with little polarization sensitivity.

► The beamsplitters are fairly insensitive to changes in angle of incidence. Peformance is relatively flat across a large spectral band.

Transmission: 45% ±5%

P– and S– components matched to within 5% for both ranges.

Absorption: <10%
