An achromatic lens is a lens that is designed to limit the effects of chromatic and spherical aberration,and is corrected to bring two wavelengths (typically red and blue) into focus on the same plane ...

One of the oldest problems in optics has been solved. Rafael Gonzalez from Mexico's Tecnologico de Monterrey has come up with an almost comically dense equation that can be used to almost completely ...

Apochromatic (APO): A lens group designed to correct chromatic aberrations for three wavelengths (usually red, green, and blue) rather than just one or two. Aspheric: A lens element with a ...
