Another type of reflecting prism is the Rhomboid. These Rhomboid prisms in effect acts as a pair of mirrors, light enters one end is then displaced laterally the opposite end. Rhomboid prisms rely on total internal reflection and input and exit faces are generally left uncoated, however these faces can be aluminized to increase the angular range.
Rhomboid prisms are supplied in a range of glasses including UV grade fused silica for UV applications working at 175nm.
