Detailed Description
Achromatic doublet lenses have significantly better optical performance than singlet lenses in visible imaging and laser beam manipulation applications. Achromat Lenses are consist 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. We provide achromatic lenses consisting of two elements. These lenses have considerably reduced not only chromatic aberration bust also spherical aberration and coma aberration. These are designed with respect to three wavelength 480.0nm, 546.1nm and 643.8nm.
