Dichroic prism Cube beam Compared with the flat beam splitter, the splitter has the same path length of reflected and transmitted light.
Product Description
The cubic beamsplitter prism is coated with a layer of film on the slope of the right-angle prism, and then glued together with a similar right-angle prism to form a cubic beamsplitter. The astigmatism of the flat beam splitter can be avoided, the coating is not directly exposed, and it is not easy to be damaged and corroded.
A polarizing beamsplitter is an optical element that splits a beam of incident light into two beams of light whose propagation directions are perpendicular to each other, while a depolarizing beamsplitter splits the incident light according to a calibrated splitting ratio without changing the polarization state of the incident light. are the transmitted and reflected beams.
Shanghai Optics produces high-precision beam-splitting prisms, including single-wavelength or broadband polarization beam-splitters, high-power polarization beam-splitters (PBS) and depolarization beam-splitters (NPBS) .
