Intended primarily for biological applications, it is designed to work with microscopes using 160mm tube-length and 45mm parfocal distance. Achromatic correction provides improved color accuracy and resolution. crystal crystal meanings An achromatic lens or achromat is a lens that is designed to limit the effects of chromatic and spherical aberration. Achromatic lenses are corrected to bring two wavelengths (typically red and blue) into focus on the same plane. Wavelengths in between these two then have better focus error than could be … See more Theoretical considerations of the feasibility of correcting chromatic aberration were debated in the 18th century following Newton's statement that such a correction was impossible (see History of the telescope). … See more Lens designs more complex than achromatic can improve the precision of color images by bringing more wavelengths into exact focus, but require more expensive … See more Several different types of achromat have been devised.
