PRODUCT
Detail
The beamsplitter plate is an optical component that decomposes incident light into transmitted and reflected light in a certain ratio through an optical coating. The incidence of angle of beam is usually 45° . One side is coated with a partial reflection coating, another side is coated with an anti-reflection coating. It can split the incident light into two parts: reflected light and transmitted light.
