Beamsplitter

BRD Optical Co. Ltd. has state-of-the-art, modern technology machines for manufacturing and inspecting all kinds of precision optics. Our company occupies an area of 2,000 square meters, supported by 120 workers. BRD Optical as one of the best precision optical components companies was founded in 2004, and is located in the city of Changchun-the optic base of China with a beautiful view and profound optical culture.

Polarizing cube beamsplitters split randomly polarized beams into two otehogonal, linearly, polarized compoments, S-polarized light is reflected at a 90® while P-polarized light is transmitted. Each dichroic beam splitter cube comsists of a pair of percision high tolerance right angle prisms cemented together with a dielectric beam splitter coating on the hypotenuse of one of prisms.

Description Of dichroic cube beam splitter
Polarization Cube Beamsplitter
Polarizing Cube dichroic beamsplitters split randomly polarized beams into two orthogonal, linearly, polarized components, S-polarized light is reflected at 90® while P-polarized light is transmitted. Each infrared beam splitter consists of a pair of precision high tolerance right-angle prisms cemented together with a dielectric coating on the hypotenuse of one of the prisms.

High Powe Cube Polarization Beamsplitter
High power polarization broadband beam splitter can be fabricated by BRD Optical. Same as the above, it uses precision optical contacted technology which makes it has a high laser damage threshold.

High Damage Threshold>500MV/cm2
Transmission >96% @ Central Wavelength
Extinction Ratio>1000:1
