NPBS/non-polarizing beamsplitter/beam splitter prism

Description

Beamsplitter Cube is a more sophisticated type consisting of two right- angle prisms cemented together at their hypotenuse faces.The cemented face of one prism is coated.Beamsplitter is often used in Plumb Level, Surveying, Alignment, Rangefinding and Optical Tooling.Before cementing,with a metallic or dielectric layer having the desired reflecting properties,both in the percentage of reflection and the desired color.The absorption loss to the coating is minimal and transmission and reflection approach *0%.
