Paper Abstract

Spectacle lens is a very particular optical imaging element of great practical importance. Although its construction is very simple some demands are specific (in particular remarkable shift of output pupil). A number of classic spectacle lens designs is known for long time, however some new possibilities of aberration correction appear if we use a hybrid (diffractive refractive). Hybrid lens is an optical system composed of a classic refractive (glass) lens and a diffractive microstructure deposited on one of its surfaces. Imaging properties of such lens can be expressed in terms of dimensionless parameters(formula available in paper)(describing the distribution of focusing power between diffractive and refractive part). By proper choice of parameter η we can compensate chromatic aberration. Thanks to other free parameters spherical aberration and astigmatism can be corrected also what is reasonable choice for spectacle lens. In this contribution the possibilities of particular Seidel aberration correction of hybrid lens will be presented. As an illustration some examples of spectacle hybrid lenses will be shown and its imaging characteristics compared with imaging characteristics of commercially available refractive lenses.
