The penta-prism is a constant deviation prism. It means that the same exact 90-degree deflection of light beam is kept regardless of the angle between these light beam and the optical axis. They are often used in range finder, surveying and alignment. Various sizes and precision of the penta prism can be made according to customer’s specifications.
