Achromatic doublet
lenses have significantly better optical performance than
singlet lenses in visible imaging and laser beam manipulation
applications. Achromatic 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. Simphoton
provides 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.
