Products Description:custom as request


From prototype to production, Focus Technology manufactures and coats prisms, it’s scope covers Penta Prism, Right Angle Prism, Beamsplitter Penta Prism, and Corner Cube, Dove Prism and Roof Prism, etc.

Right-angle prism is usually used as a mirror to deviate light through 90 degrees and as a reflector to deflect light through 180 degrees by total internal reflection, which is widely used in telescope, periscope and other optical systems.
