Achromatic doublet lenses are designed to eliminate chromatic and spherical aberrations inherent in singlet lenses. When used on-axis, an achromatic lens focuses an parallel input beam to a perfect "point", limited only by the effects of diffraction. They can also be used for high-quality imaging on-axis. However, the off-axis performance is significantly worse than the on-axis performance.

Optical glass achromatic doublet lenses
Achromatic doublet lenses are designed to eliminate chromatic and spherical aberrations inherent in singlet lenses. When used on-axis, an achromatic lens focuses an parallel input beam to a perfect "point", limited only by the effects of diffraction. This performance can be achieved over a broadband of wavelength. Achromatic lenses can be used to collimate and focus laser beams. They can also be used for high-quality imaging on-axis. However, the off-axis performance is significantly worse than the on-axis performance. If your application requires good optical performance off-axis as well as on-axis, multi-element lenses such as our digital imaging lenses are recommended.
