Higher-order kinoforms

Several arguments are made for using higher-order, rather than first-order, kinoforms for producing low f-number diffractive lenses. It is shown that improved efficiency can be achieved with higer-order kinoforms when the f-number of the lens is very low. A procedure for the fabrication of higher-order kinoforms is also presented.
