Before revision: A dialyte lens (sometimes called a dialytThe optics encyclopedia, Volume 4 edited by Thomas Gordon Brown ) is a compound lens design that corrects optical aberrations where the lens elements are widely air-spaced.Michael Bass, Casimer Decusatis, Vasudevan Lakshminarayanan, Handbook of Optics, Third Edition Volume I: Geometrical and Physical Optics, page 25 The design is used to save on the amount of glass used for specific elements or where elements can not be cemented because they have dissimilar curvatures.Fred A. Carson, Basic optics and optical instruments, page AJ-4 The word dialyte means "parted", "loose" or "separated".Peter L. Manly, Unusual Telescopes, page 55 Dialyte telescopes

Carson, Basic optics and optical instruments, page AJ-4 The word dialyte means "parted", "loose" or "separated".Peter L. Manly, Unusual Telescopes, page 55 DesignIn its simplest form, a dialyte can be formed by separating the elements in a cemented achromatic doublet of positive and negative lenses, although the powers of the individual elements must be increased to compensate.
