Product Description

Refractive prism used to invert images by 180°. Light enters/exits normally, so no dispersion occurs.

Typically 30°/60°/90° prisms with a reflective coating on the hypotenuse to deviate the line of sight by 60°.

Used in pairs to transform elliptical laser diode beams into nearly circular beams. Achieve ~95% throughput at Brewster angle.

Used to invert and revert images while bending the line of sight by 90°. Includes Schmidt and Pentagonal roof types.

Ideal for image rotation and inversion. Can also act as a retroreflector similar to a right-angle prism.
