Penta prisms are five-sided prisms featuring a ray deviation of 90° and a right handed image. The reflecting surfaces are aluminized for increased efficiency. Slight movement of the prism does not affect the true right angle at which light rays are reflected, making a penta prism the ideal optical tool for defining a right angle in an optical system.
Half Penta prisms are used to deviate the line of sight by 45° without inverting or reverting the image. The reflecting surface is
aluminized and over-coated with Inconel and black paint to increase efficiency.
