Telescope object glass that has been highly corrected for color error (chromatic aberration). The typical achromatic lens brings two colors (usually red and blue) to a common focus by using two different types of glass in combination. In an apochromat, three lenses are used, thus bringing a third color, usually violet, to the same focus. 1, record 2, English, - three%20element%20apochromat
