Advantages:  Right angle prism is deviating or deflecting a beam of light with 90or 180

Applications:                    

• Right angle prisms are available in either BK7 or UV fused silica.BK7 prisms are recommended for general laboratory use in  the visible and near IR.For UV,infrared,or thermally sensitive applications Fused Silica prisms are advised.
• 180 deflection uses with hypotenuse as the entrance and exit face. The main application is as a retro-reflector provided that the plane of incident beam includes the vertex.
• Right angle prism is often used in telescope, periscope and other optical system.

Specification:

* Other sizes, and coatings are available upon requirements.
