Prisms

Optical Prisms for Beam Steering and Spectral Dispersion

Optical prisms are precision-polished glass blocks with flat surfaces set at controlled angles, used to deflect, invert, rotate, disperse, or fold a light beam without a lens's focusing power.

Ross Optical manufactures right-angle, equilateral, dove, amici, wedge, and penta prisms, along with retroreflectors, each suited to a specific beam-steering function:

• Right-angle and penta prisms for 90° beam deflection in periscopes and rangefinders

• Dove and amici prisms for image rotation/inversion in telescopes, binoculars, and endoscopes

• Equilateral prisms for spectral dispersion in spectroscopy

• Wedge prisms for beam steering and alignment

• Retroreflectors for return-beam applications such as laser range finding and optical alignment

Custom angles and coatings are available for specialized system requirements.
