The following information is about Achromat.
Achromat Defined
A type of refractor objective made from lenses -- usually two -- of different materials, selected to bring two colors of light -- usually blue and yellow -- to the same focal point, thereby bringing the rest of the colors of visible light to very nearly the same focal point, thus making a decent stab at being in focus for all colors of visible light at the same time. That is, an achromat attempts to reduce longitudinal chromatic aberration.
An achromat will also have spherical aberration corrected at one wavelength of light -- usually green.
This definition is in context to Telescope. See more contextual defintions for Achromat.
