Design of diffractive optical elements for multiple wavelengths

摘要

A method for producing diffractive optical elements (DOE's) for multiple wavelengths without chromatic aberration is described. These DOE's can be designed for any distinct wavelength. The DOE's are produced from two different optical materials, taking advantage of their different refractive indices and dispersions. (C) 1998 Optical Society of America. [References: 7]
