Optical Prisms are used to redirect light at a designated angle. Optical Prisms are ideal for ray deviation, or for adjusting the orientation of an image. When light enters an optical prism, it either reflects off an individual surface or several surfaces before exiting, or is refracted as it travels through the substrate.
JSoptical Prisms include:
Right Angle, Amici, Penta, Beamsplitter Penta, Schmidt, Porro, Wedge, Brewster, Anamorphic, Equilateral, Roof, Dove, Rhomboid prisms, Corner Cube Retroreflectors or Light Pipe Homogenizing Rods and customized special shaped prisms etc.
Light Pipe Homogenizing Rods are optical components designed for any application that requires homogenized light.
Light pipe utilize total internal reflection to homogenize non-uniform light sources, and it can be used for mixing and homogenization of one or more point sources, regardless of their individual spectral characteristics.
Hexagonal configuration of the light pipe provides 35% less light is lost in completing the clear aperture than would a comparable square configuration.
Fused Silica Light Pipe Homogenizing Rods are ideal for applications utilizing UV LED light sources.

Diode lasers usually feature an elliptical beam profile. While, mostly a circular beam shape is required, like mode-matching to an external resonator, adapting beam size to pass a small aperture of an isolator, and etc.
Anamorphic Prism Pairs are used to transform elliptical laser diode beams into nearly circular beams by magnifying the elliptical beam in one dimension.

Rhomboid prism can displace a laser beam without change the image orientation, the input beam is totally internal reflected by two 45degree faces and goes out from the output face. Then, a lateral displacement is produced.
Higher transmission rate can be achieved by anti-reflective coating on the input and output faces.
Rhomboid prism is always used in stereoscopic system and periscope system.

Brewster prism is one kind of dispersion prism, it is normally used to separate two wavelengths following the same beam path.
Brewster prism is designed specifically for intra-cavity laser application, the beam enters and exits the prism at Brewster's angle, minimizing intra-cavity losses.

Porro prism is a type of reflection prism which can be used to alter the orientation of an image.
Beam enters the large face of the prism, and 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 180deg but not inverted.

Corner Cube Retro Reflector operates on the principle of Total Internal Reflection (TIR). An incident beam will be reflected parallel to itself by the three roof surfaces. The reflection is insensitive to the incident angle, even when the incident beam enters the prism off normal axis, there will still be a strict 180deg reflection.

Penta prism has five sides, four of them polished. Two reflective sides are coated with metal or dielectric HR coating and these two sides can be blackened. The deviation angle of 90deg will not be changed if the penta prism is slightly adjusted, this will be convenient to install it.
Penta prism widely used in laser level, alignment and optical tooling.
The reflecting surfaces of this prism must be coated with a metallic or dielectric reflective coating.
