Optical prisms

Right Angle Prisms
Right Angle Prisms 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 0.16-2.10μ 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.
