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.
