Aspheric Achromatic Lens
An achromatic lens is a lens that is designed to limit the effects of chromatic and spherical aberration,and is corrected to bring two wavelengths (typically red and blue) into focus on the same plane.

CaF2 Fused Silica CaF2 Triplet Lenses
Triplet achromatic lenses offer excellent performance in chromatic and aberration correction and are suitable for high precision optical systems, but have higher cost, weight and assembly complexity. The choice needs to be weighed against the specific needs of the application.
Triplet achromatic lenses made of fused silica(SiO2) and calcium fluoride(CaF2) materials are used to correct chromatic aberration mainly through the different dispersion characteristics of these two materials.

Triplet Lenses
A triplet lens is cemented by one piece of crown glass with low refractive index and two pieces of flint glass with high refractive index, normally the cemented lens can eliminate spherical chromatic aberration of axial direction.
