The Achromatic Lens consists of a positive low-index Crown Glass lens element cemented to a negative high-index Flint Glass lens element. It is designed to cancel chromatic aberration at two wavelengths, eliminating focal length shifts across visible wavelengths.

This spherical lens is designed to transmit and refract light, either converging or diverging the beam. Compound versions use multiple elements to correct optical aberrations more effectively than single-element lenses.
