Our Dispersive Equilateral Prisms, which are fabricated from BK7/K9, Fused Silica, N-SF11, F2, CaF2, or ZnSe are available in sizes ranging from 10 mm to 80 mm. These prisms create less stray light than diffraction gratings, thereby eliminating the higher order problems typically associated with gratings.
Dispersive prisms are typically used at the minimum angle of deviation. This is the angle for which the wavelength of interest will travel parallel to the base of the prism, and the angle of incidence is equal to the angle of refraction when measured with respect to the normal of the prism face at the respective interface. At the minimum angle of deviation, a maximum clear aperture is achieved and reflective loss of P-polarized light is reduced since the angle of incidence is nearly Brewster's angle. For S-polarization, a custom antireflective coating can be used to minimize surface reflections.
