The optical beam splitter cube prism is mainly divided into polarization beam splitter prism and depolarizing beam splitter prism, which can be produced according to customer requirements.
Cube Beamsplitter Prism is made of 2 right-angle prisms. One of the right-angle prisms has a dielectric light-splitting film layer on it. When the light is incident perpendicularly to the incident surface, the outgoing light is divided into two polarized lights. Among them, P light is transmitted light, and S light is reflected light. After the beam splitting prism splits the original horizontal polarization and vertical polarization in the incident light as much as possible, the optical characteristics of P light and S light have a separation of < 5%, low dispersion, and good color neutrality.
