Optical Prisms are useful for folding a system's optical path or rotating images. Optical prisms are available in a variety of geometries, each producing a different optical result. Kristin Vogt, Product Marketing Manager, explains important concepts to remember when choosing a prism in this easy-to-follow product review video. For more information, read our Introduction to Optical Prisms and Optical Prism Application Examples application notes.
Prisms are useful for folding optical systems or rotating images. Each Prism Type has a specific angle that the light path bends . Prisms can be used to invert and revert images depending on the application. SLR cameras and binoculars both use prisms to make sure that the image you see is at the same orientation as the object. One important thing to keep in mind when selecting a prism is that the beam reflects off of multiple surfaces within the optic. This means the optical path length through the prism is much longer than it would be with a mirror.
