Abrégé
(EN)
Circular and annular lens zones are disclosed which, at a given lens area, exhibit a depth of focus of a lens of considerably smaller area. The large depth of focus is achieved by imparting the lens zones a refractive power profile. An assembly of such large depth of focus lens zones represents a lens of large diameter which lens, in polychromatic light, exhibits essentially the same depth of focus as the lens zones from which it is composed.
(FR)
L'invention concerne des zones circulaires et annulaires de lentille qui, avec une superficie donnée, présentent une profondeur focale équivalente à celle d'une lentille ayant une superficie considérablement inférieure. La grande profondeur focale est obtenue en donnant aux zones de la lentille un profil de puissance de réfraction. Un assemblage de ces zones de lentille avec une grande profondeur focale représente une lentille de grand diamètre qui, sous une lumière polychromatique, présente sensiblement la même profondeur focale que les zones de lentille qui constituent l'assemblage.
