    Optical Prisms

    • Product Name: 90 Degree Bending Prisms

    Product overview

    90 Degree right angle bending prisms utilize the inherent total internal reflec-
    tion (TIR) at the hypotenuse to invert the image and achieve a 90°change
    in direction. Antireflection coatings are applied to the two legs of a standard
    right angle prism(RAP) to maximize the overall throughput and reduce back-
    reflections off the interfaces to near zero. Because the internal reflection is
    independent of wavelength. these prisms can also be used as high energy
    900 reflectors for broadband applications where metal mirrors are too ab-
    sorbing and dielectric mirrors do not reflect a wide enough bandwidth. The
    Applications include UV beam routing. beam pick off, and variable delay
    lines as well as broadband. high energy 90°reflectors. High energy AR and
    BBAR coatings are applied to Legs. Scitlion also offer other dimensions
    and wavelengths in prototype and production quantities.
