In many situations involving collimated light, prisms are superior to mirrors for deflecting light. Prisms, because of their shape accuracy, require less positioning than mirrors. Light is always reflected within the plane parallel to the ground face of the prism. Also, because light is reflected by total internal reflection, prisms can be used to reflect high power laser beams that might otherwise damage sensitive coatings.
