Beamsplitter Penta Prism
Right Angle Prism
Corner Cube Prism
Right Angle Prism : are precision polished to light tolerances for more demanding applications. They 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, infraved, or thermally sensitive applications Fused Silica prisms are advised. Our Fused Silica prisms are manufactured to exacting specifications and are useful from 0.16-2.10 μ m.
Right angle prism is deviating or deflecting a beam of light with 90° or 180°.It is often used in telescope, periscope and other optical system.
90deg Deflection: 90 deg deflection occurs at the face. The hypotenuse image is erected and reversed.
180 deg Deflection: 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.

Corner Cube Retroreflectors
These Prisms have 3 mirror surfaces making angle of 90 to each other,juxtaposed to form corner of a cube with the entrance face perpendicular to cube diagonal. All beams, despite of incident direction,are reflected back to the original direction. Corner cubes are used in high precision applications or with lasers over very long distances. These angle insensitive mirrors therefore find frequent applications in situations where orientation is difficult or impossible to control and where a mirror would therefore be unsatisfactory.
