An achromatic lens is a lens that is designed to limit the effects of chromatic and spherical aberration. Achromatic doublet lenses have significantly better optical performance than singlet lenses
in visible imaging and laser beam manipulation applications. We provide custom achromatic lens consisting of two elements, usually of a positive low-index crown glass cemented to a negative
high-index flint glass that have been corrected for chromatic aberration with respect to two or more selected wavelengths.
