There is a wide variety of prism options however the Right-angle prism is the most common type of prism. The Right-angle prism is a 45°-90°-45° prism used to re-direct a beam of light through a right angle with the surfaces forming the 90° angle acting as transmitting faces. They are often coated with various optical coatings to form cubic beam splitters and color separation cubes used in various projection systems.
- Variety of materials such as BK-7, fused silica, Schott and Ohara glass types.
- Commonly used in imaging systems and in laser applications.
- High transmission can be achieved, using the hypotenuse face in total internal reflection (TIR), with an antireflection coating on the entrance and exit faces.
- Images will be correct (left-to-right), inverted, or erect and reversed (left-to-right)
