Right angled prism of 90 degree, hot sale prism products 10 *10*10

A 30-60-90 right triangle (literally pronounced "thirty sixty ninety") is a special type of right triangle where the three angles measure 30 degrees, 60 degrees, and 90 degrees.

Right-angle prism is the most common type of prisms. It is used to re-direct a beam of light at 90 degrees from the the incident direction or used as a 180 beam retro-reflector.  They are often coated with various optical coatings to form cubic beam splitters and color separation cubes used in various projection systems.

• High transmission can be achieved, using the hypotenuse face in total internal reflection (TIR), with an antireflection coating on the entrance and exit faces.
• The prism can be used as an internal or external mirror by applying a metallic coating on the hypotenuse.
• We also offer fused silica prisms, and precision grade and ultra-precision grade glass prisms with tighter manufacturing tolerances.
