Paper Abstract

Diffractive lenses are generally quite sensitive to changes in wavelength. An expression for the spectra of thin diffractive lenses is derived from the Fresnel diffraction integral. Spectra computed with this expression are compared with spectra obtained from computed diffraction patterns. Based on a new definition for the bandwidth of a thin diffractive lens, an expression for this bandwidth is derived.
