Precision Optical Glass Achromatic Lenses (Doublets)

Achromatic lenses (doublets) consist of a positive, low-index crown glass element cemented to a negative, high-index flint glass element. The elements are chosen to cancel chromatic aberration at two well-separated wavelengths, usually in the blue and red regions of the spectrum. The focal length is constant at those two wavelengths, and focal length shifts are virtually eliminated across the visible spectrum. One common use is diffraction-limited focusing of a laser beam. Negative achromats are typically used when chromatic aberration must be eliminated. In addition to reducing chromatic aberration at the design wavelengths, spherical aberration and coma are greatly reduced.
