Product Description
Achromatic photography lens
Achromatic photography lens is designed to eliminate chromatic and spherical aberrations inherent in singlet lenses. When used on-axis, an achromatic lens focuses a 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.
Achromatic lens can be used as collimators, focusing lenses or light collectors. They are designed to eliminate chromatic and spherical aberrations and perform well for all paraxial imaging tasks. These lenses are coated with single layer antireflection coating to reduce surface losses in the visible regions.
Achromatic lenses are widely used today in achromatic telescopes, microscopes, and photographic lenses.
