1. (General Physics) Also called: achromatic lens a lens designed to bring light of two chosen wavelengths to the same focal point, thus reducing chromatic aberration. Compare apochromat

The APS-U storage ring will feature a new design, a multi-bend achromat lattice, with many more bending magnets and magnet-focusing cells than the present machine, resulting in brighter X-ray production.
For example, a complete achromat might believe that ripe tomatoes are red without grasping this proposition.
At that time, founder Norman Edmund sold a pcx lens for 10 cents and an achromat for 25 cents.
All precipitates were scanned and imaged using a helium/neon-laser (wavelength: A = 632.8 nm), a 63x plane achromat oil immersion objective, a 90/10 mirror, and the LSM AF lite software version 1.0.0 (Leica Microsystem, GmbH).
The NIS optical system provides sharp, crisp images via Plan achromat or S-Plan APO objectives.

A new configuration will be tried at Diamond, a Double Double Bend Achromat. This will result in one cell, the machines, all of the magnets and vacuum vessels being removed and replaced to a new configuration.

The chromatic aberration of the Lowell 24-inch [610mm] f/16 Clark refractor exceeds that of a 6-inch [152mm] f/5 achromat, so it is hardly surprising that a dense yellow Wratten 15 filter was employed whenever lunar mapping was conducted.
