Introduction

90°reflectors

TIR or protected Aluminum coating

Right angle bending prisms work effectively by total internal reflection. They 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.
