Right Angle Folding Prisms

Optola offers wide range of right angle folding prisms.

Custom design right angle folding prisms are available upon request.

  •   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.
