Penta Prism 10 - 10 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
Penta Prisms are used to deviate an incident beam through 90° without inverting or reversing it. They are 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 accuracy of the 90° deviation of a Penta Prism is only dependent on the manufacturing tolerances of the prism.
The Penta Prism is optimized for the wavelength range of 400-700 nm.
The dimension tolerance of the Penta Prism is +0 / - 0.254 mm.
Dove Prisms are a truncated form of right angle prism. They use total internal reflection to produce an inverted image which emerges without any beam deviation. The main application for these prisms are as image rotators.
