Custom Right Angle Prisms

Custom right-angle prisms are utilized in a wide range of applications such as imaging systems, periscopes, surveying instruments, laser systems, and more. The ability to customize materials, coatings, sizes, and angles makes them versatile tools in optical design. It’s an optical element with a rectangular cross-section that has three mutually perpendicular faces, with two of the faces forming a 90-degree angle.
