We developed the diffractive optical elements (DOEs), named the multi-layer DOEs, to operate with visible wavelength. First we report the principle of the multi-layer DOEs. Second, the application to the imaging lens system is reported. The imaging lens system with the multi-layer DOEs, EF400 mm F4 DO IS USM, is very compact (233 mm) and light (2, 080g).
