Penta Prism 20 - 20 mm
Description
Penta Prisms deviate an incident beam through 90° without inverting or reversing it. They also show constant deviation (i.e. the beam is deviated through 90° irrespective of the orientation of the prism). The accuracy of the 90° deviation is therefore only dependent on the manufacturing tolerances of the prism. These prisms are extremely useful when precise orientation of the prism is not possible and also where the path length through an instrument needs to be shortened. Typical applications include range finding, surveying, alignment, and cinephotography. The reflecting faces are coated and the entrance and exit faces have an antireflection coating optimized for 400-700 nm.

Frequently Asked Questions
A Penta Prism is an optical instrument that deviates an incident beam through 90° without inverting or reversing it.
The accuracy of the 90° deviation in a Penta Prism is dependent only on the manufacturing tolerances of the prism.
Some typical applications of Penta Prisms include range finding, surveying, alignment, and cinephotography.
The antireflection coating on the entrance and exit faces of a Penta Prism is optimized for 400-700 nm.
A Dove Prism is a truncated form of right angle prism that uses total internal reflection to produce an inverted image which emerges without any beam deviation.
