•   Total internal reflection prisms.
•   180° beam deflection.

•   Our Right Angle Folding Prisms are also available with antireflection  coating on hypotenuse in order to reduce surface loss.
•   Coating specifications upon request.
•   Other sizes and coatings are available upon request. 

Example: The legs 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.
