Cube Beamsplitter
Beamsplitters Cube 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 to your online ordering, we recommended that you select from our Polarization Beamsplitter Cube(PBS) or Non-polarization Beamsplitter Cube(NPBS).

Broadband Polarizing Beamsplitter Cubes
Beamsplitters are optical components used to split input light into two separate parts. Beam splitters are common components in laser or illumination systems. Beamsplitters are also ideal for fluorescence applications, optical interferometry, or life science or semiconductor instrumentation. Light can be split by percentage of overall intensity, wavelength, or polarization state.
