Abstract

We study the focusing efficiency of multilevel diffractive lenses as a function of f-number. Both scalar and rigorous analyses are performed on two- and three-dimensional lenses. We show that shadowing in lenses with small f-numbers is a critical factor that limits their performance. We show further that scalar analysis does not accurately predict the effects of shadowing for lenses with long f-numbers and large numbers of phase levels.
