Equilateral Prisms


Equilateral Prisms are available in both Laser Quality and Analytical Quality polish designated as LQ (Laser Quality) and AQ (Analytical Quality). 

Equilateral Prisms are available in BK7 Glass & UV Fused Silica.  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.

For more information about Prisms, refer to our
Optics Tutorial page.
