Achromatic Lenses

achromat lensUse Achromat lenses to minimize or eliminate chromatic aberration. The achromatic design also helps minimize spherical aberrations. An Achromat Lens, is designed by either cementing two elements together or mounting the two elements in a housing, creates smaller spot sizes than comparable singlet lenses. Achromatic Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy.

Achromatic doublet lenses (“achromat”) 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.

For some applications it is desirable to have a high-quality lens with a lower f/# (for example, collimating a diode laser with large divergence angle). This can be done by adding a matching aplanatic meniscus lens to a doublet lens. An aplanatic meniscus lens will shorten the focal length of the doublet lens (thus, lowering the F-num) without introducing additional spherical aberrations.
