DO (Diffractive Optics) Lens (CG)

DO (diffractive optics) lens elements enable telephoto lenses to be lighter and more compact while maintaining a high level of performance. Canon succeeded in creating the innovative DO lenses by bonding a precise diffraction grating to the surface of a glass lens. This video introduces the mechanics of DO lenses, highlighting the construction of dual- and triple-layer DO lenses.
