HotanPolarizing beam splitter (PBS)
Product Description
A polarizing beam splitter prism can split an incident unpolarized light into two perpendicular beams, where P-polarized light is completely transmitted, and S-polarized light is reflected at a 45-degree angle, with the outgoing direction forming a 90-degree angle with the P-light. This polarizing beam splitter prism is made of a pair of high-precision right-angle prisms, one of which has a polarizing beam splitting film coated on its hypotenuse.
Chuangyu Optoelectronics can provide two types of high-precision polarizing beam splitter prisms. One is cemented PBS, which uses a cement method for the hypotenuse, and the other is high-power PBS, where the interface of the PBS is optically bonded. The specifications of the two PBS are as follows:
