Roof prisms

Roof prism is the hypotenuse surface of right anlge prisms are replaced by the reflective surface mutually vertical, a totally internally reflecting roof attached to hypotenuse surface. It can invert and reverse an image, also, deflect the image 90 degree. Therefore, the degree of cleaning and quality of wedge surface are very important. it is often used in terrestrial telescopes, viewing systems and rangefinders.This typeprisms can be used on Terrestrial telescope, Imaging system, Viewing system, Range finder.
