    Right Angle Prisms,Uncoated

    Total internal reflection prisms
    90°or 180°beam deflection

    Right Angle Bending,Prisms

    90°reflectors
    Right angle bending prisms are anti-reflection coated on the legs. Optionally, the hypotenuse may be coated with second-surface aluminum protected by black sealing paint to ensure grazing incidence reflection. These prisms are suitable for optical delay lines and for high power use.


    Right Angle Folding Prisms

    180°reflectors
    Aluminum on legs and AR on hypotenuse
    Folding prisms are intended for use as 180°reflectors. An anti-reflection coating is applied to the hypotenuse. Second-surface aluminum protected by black sealing paint is applied to the legs to ensure grazing incidence reflection. These prisms are suitable for optical delay lines and for high power use.
