  Achromatic Lens is an achromatic consists of a positive
low-index Crown Glass lens element cemented to a negative
high-index Flint Glass lens element. The elements are chosen so as
to cancel chromatic aberration at two well-separated wavelengths,
usually in the blue and red region of the spectrum. Focal length is
constant at those two wavelengths and focal length shifts are
virtually eliminated across the visible wavelengths. One frequent
use is to achieve diffraction limited focusing of a laser beam.
Negative Achromats are typically used when there is a need to
eliminate chromatic aberration. In addition to reducing chromatic
aberration at the design wavelengths, spherical aberration and coma
are greatly reduced.
