There exist various types of optical prisms, each possessing a specific geometry to achieve the necessary reflections for performing a particular imaging task. Reflecting prisms may invert, rotate, deviate or displace a beam while dispersing prisms produce spectral separation for spectroscopic applications or tuning laser output. Ost Photonics offers a diverse range of high-precision prisms, including Penta Prism, Beamsplitter Penta Prism, Right Angle Prism, and Corner Cube. Our micro Penta Prism and Right Angle Prism are widely utilized in optical communication applications such as optical switches. Additionally, we can provide other types of prisms upon request, such as Dove Prism and Roof Prism.
Penta prism can deviate an incident beam by 90° without inverting or reversing, and this deviation angle remains constant regardless of any rotation of the prism about an axis parallel to the line of intersection of the two reflecting faces. It is commonly used in plumb level, surveying, alignment, range finding and optical tooling.
Corner Cube Prism is also called Retroreflector or Trihedral Prism. In the Corner Cube Prism, three reflecting surfaces are perpendicular to each other, like the side wall of the cube. The input surface is perpendicular to the cube diagonal. Disregarding the angle of incidence, the output beam is parallel to the input one, but it is of opposite direction.
A right-angle prism serves as a mirror to deflect light at a 90-degree angle and also functions as a reflector to redirect light by total internal reflection over an angle of 180 degrees.
