By far, the most commonly used prisms are 45°-90°-45° prisms, commonly known as right angle prisms. It can achieve different results related to image parity or bias in a number of ways, so named because of the angles on its triangular faces. The most common application for a 45°-90°-45° prism is to think of it as a right angle prism, which has only one reflection that deflects the incoming ray by 90°. The resulting image will become left-handed, but can be reversed or restored depending on the position of the prism.
Right-angle prisms can achieve 180° and 90° rotation of light through the internal reflection of right-angle surfaces or inclined surfaces. They are widely used in imaging systems, and high-precision right-angle prisms are also very suitable for the laser industry.
0.5mm microprism or 100mm microprism can be customized according to customer needs.
