The micro prisms are right angle, 45°- 90°-45° prisms, whose sizes range from 0.5 mm to 5.0 mm with a format of A=B=C. These right angle prisms are used to deflect a light beam 90° or 180° as shown to the left. Depending on prism orientation, images will be inverted, but correct left to right. If the prism is rotated 90°, images viewed through it will be erect, but reversed left to right. Coated prisms can also be used as mirror reflectors with respect to incoming light. Uncoated prisms act as mirrors for light incident on one of the short sides since incident light is totally internally reflected at the hypotenuse.
