Commercial Grade Penta Prisms
1. Over View
Penta Prisms: The penta is a five-sided prism. It reflects light rays through a 90° angle by two reflections and does not invert or revert the image. The reflecting surfaces are aluminized. Slight movement of the prism does not affect the true right angle at which light rays are reflected. It also shortens the optical path length of an instrument.
2. Application
Distance measurement
Optical signal process
Laser
