Product Description

Tower Optical Corp. has expanded its line of precision optics to include standard micro prisms, coated and uncoated, for use with laser sources and imaging applications. The micro prisms are right angle, 45°-90°-45° prisms, whose sizes range from 0.5mm to 5.0mm with a format of A=B=C.

These Right Angle Prisms are used to deflect a light beam 90° or 180° as shown above. 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.
