optics of diffractive multifocal iol

the diffractive multifocal iol provides simultaneous bifocal imaging by utilizing both diffractive and refractive optics. in both distant and near vision, there is a clear highly focused image on the retina. the second image is highly defocused, providing only faint background illumination. a small amount of the light goes to the higher orders of diffraction which are not perceptible by eyes. t...

Commercial aspects of diffractive optics

The purpose of this article is to provide the reader with an up-to-date status on the commercial applications of diffractive optical elements. Rather than merely treating these as individual components, this article will also focus on the their applications from a systems point-of-view. Diffractive optics − an introduction Diffractive optics, as the name implies, are based on the principle of d...
