Right Angle Prism
Right Angle Prism may be used as a 90 degree reflector or 180 degree retroreflector. The prism deflect, deviate and rotate beams of light as well as dispersing their wavelengths. They usually used for beam deviation or as substrates for beam splitters. We also provide other optical prism such as roof prism.

Paul prism
Paul prism is a type of reflection prism which can be used to alter the orientation of an image. Light enters the large face of the prism, then hits on the roof, by total internal reflection twice from the roof, the beam exits again through the large face. An image traveling through a porro prism is rotated by 180 but not inverted.
