It composed of birefringent crystals of two different materials, due to the different dispersion of the two materials, a relatively uniform phase retardation can be achieved in a wide wavelength range. Due to the uniform and flat wavelength response of achromatic wave plates, they can be used in tunable lasers, multi-wavelength laser systems and other broadband light source products
