Beamsplitter Cube is a more sophisticated type consisting of two Right Angle Prism cemented together at their hypotenuse faces.The cemented face of one right angle prism is coated. Beamsplitter cube 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 50%.
We supply many other types of high precision optical Glass Prism,such as Wedge Prism,right angle prism,Roof Prism,rhombohedral prism,Dove prism,Penta Prism,pyramid prism,Dispersion Prism,Corner Cube Prism, beamsplitter prism etc. Irregular-shaped or non-standard size optical glass prismmay be available by custom order.
