Right Angle & Equilateral Prisms

eSource Optics offers both Laser Quality and Analytical Quality Right Angle Prisms & Equilateral Prisms are available in UV Grade Fused Silica (FS) & BK7 Glass.  Right Angle Prisms are a type of 45-90-45 degree prism typically used to bend a beam of light through a right angle with the surfaces forming the 90 degree angle acting as the transmitting faces.  The most common type of prism for many applications.  Equilateral Prisms are a dispersing type of prism typically used for wavelength separation applications.  The three sides of the prism are of equal length.  A light ray is twice refracted passing through the prism with total deviation a function of prism material index of refraction, and hence wavelength.
