Optical Prism

 

Optical prism is a transparent optical element with flat, polished surfaces that are designed to refract light. At least one surface must be angled — elements with two parallel surfaces are not prisms. The most familiar type of optical prism is the triangular prism, which has a triangular base and rectangular sides. Not all optical prisms are geometric prisms, and not all geometric prisms would count as an optical prism. Prisms can be made from any material that is transparent to the wavelengths for which they are designed. Typical materials include glass,fused silica ,sapphire and fluorite.

Ricun optical manufacture all kinds of high-precision prism, including corner cube, dove prism, penta prism, penta prism beamsplitter , phomboid prism, right angle prism.Also can be provided at the request of customer.Optical prisms are widely used for endoscopes, microscopes, laser calibration,medical instruments,visual aiming, projection, measurement display system,Interferometry, axis calibration, laser tracking, precision calibration,rangefinder, laser instrument,laser beam expander, high-definition imaging system, micro display relay system.
