Tower 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 0.5 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.
