Roof Prisms
Features:
High Precision Dimension Control, Optional Substrate Material.
Applications:
Terrestrial telescope, Imaging system, Viewing system, Range finder.
Description:
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.
With the roof surface, these prisms are used to invert and reverse the image. Union Optic can provide roof right angle prisms, roof penta or half penta prisms, Schmidt prisms, or other roof prism specified by customers.
