Category: Equilateral Prisms

Prisms are optical elements with flat, polished surfaces that deflect or deviate beams of light. Esco manufactures three standard, elementary shaped product lines: Right Angle Prisms, Equilateral Prisms, and Laser Prisms.

Esco also designs and manufactures a variety of custom prism optics. With hardly any size limitations for the prisms we can build, we are able to meet all of our customers’ specific needs. If your application requires a surface quality better than that of commercially available optics, Esco can manufacture them for you. We have the ability to supply elements with surface quality better than laser grade, 10-5, or λ/20. We can also manufacture custom products with tolerances other than our standard elements.

Unless otherwise specified, all prisms are supplied uncoated. However, coatings can greatly enhance a prism’s performance. Contact us today to start your coated prism order using our online quote tool.

Customer Reviews (5.0 / 5 · 5 reviews)

Miles ★★★★★

Used it to split a laser beam for a physics demo and the deviation was clean and perfectly consistent across all three faces. The polish is genuinely flawless, no scattering or ghosting even at sharper angles.

Joseph ★★★★★

The three polished faces on this prism gave me a clean rainbow across the wall the first time I tried it with a flashlight. Edges are sharp and the glass feels solid, not cheap.

Jacob ★★★★★

Bought this to split white light into a rainbow and it does exactly that—the equilateral shape gives me three clean faces to work with, no guessing which side to aim. Edges came sharp and chip-free right out of the box.
