The history of Carl Zeiss lenses began in 1890 with the invention of an astigmatism-compensating lens called the Anastigmat. Since then, Carl Zeiss, as a lens company with 150 years of tradition, has made a name for itself in the field of optical equipment such as medical series, bifocals, camera lenses, enlarging lenses, eyeglasses, and planetariums. Among them, the camera lens has the advantages of distinctive resolution, detailed depiction, uniform aperture, and hardened treatment of T* multilayer film emission.
