Optical BK7 Glass Beamsplitter Cube/Non-polarizing cube beamsplitter

Specification of our beamsplitters as follow: *Material BK7 glass or UV grade fused silica *Dimension Tolerances: +/-0.1mm *Angle Tolerance +/-3’or 30” *Clear Aperture:90% Dimension *Surface Quality:60/40 or 20/10 *Surface Flatness:lambda/8 or lambda/4 at 633nm *Chamfer 0.3+/-0.1mm *Coating Optional 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 50%.
