View source for Kinoform

A '''kinoform''' is a type of computer-generated [[converging lens]] that is able to efficiently focus light to a point.<ref name="q789">{{cite journal | last=Jordan | first=J.

They can be used in areas such as focusing [[x-ray]] radiation, or in the study of [[nanomaterial]]s. [[Diamond]] is often used in kinoform lenses as it has a high [[thermal conductivity]].<ref>{{cite web |url= http://phys.org/news168536133.html |title=A Kinoform's Best Friend: Diamond Refractive Lenses for Nanofocusing |accessdate=12 August 2013}}</ref> Higher chromatic aberration is a common drawback.<ref name="q789"></ref>
