Right Angle Prisms
Right angle prisms are used to deviate light by 90 degree or 180 degree. Depending on the orientation of the prisms, right angle prisms produce the inverted left handed image. Utilizing the character of critical angle, highly-efficient reflection inside is one of basic function of right angle prisms. Right angle prisms are easy to be mounted, have better stability and hardness for mechanical stress, are used in telescope and other optical system.
