Product Description

Achromatic lenses are a combination of a positive low refractive index (corona crown ) and negative high refractive index (flint). Compared with monolithic singlet lens the doublet design can provide users with additional design freedom and further optimize the performance of the lens. Therefore, the advantages of achromatic lenses are more significant than those of single lenses with equal diameter and focal length.
