Our high-precision Equilateral Prisms (also known as dispersing prisms) feature three equal 60° angles, making them ideal for high-performance wavelength separation and beam refraction applications. Engineered for tight optical setups, these prisms deliver minimal distortion and excellent light dispersion across the visible spectrum.
