Dialyte lens

A dialyte lens (sometimes called a dialyt[1]: 1873 ) is a compound lens design that corrects optical aberrations where the lens elements are widely air-spaced.[2] 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.[3] The word dialyte means "parted", "loose" or "separated" in Greek.[4]
