Abstract: PCT No. PCT/FR90/00338 Sec. 371 Date Feb. 14, 1991 Sec. 102(e) Date Feb. 14, 1991 PCT Filed May 11, 1990 PCT Pub. No. WO90/13832 PCT Pub. Date Nov. 15, 1990.The present invention relates to a method of manufacture of an optical lens providing refractive index modulation, characterized in that, starting from a lens of transparent hydrophilic polymer preferably of the hydrogel type, which has previously been shaped, the lens is impregnated with a photopolymerizable composition containing at least one monomer and a photoinitiator, which are in solution in water in the case of a hydrogel, the impregnated lens is subjected to locally modulated irradiation so as to cause local selective polymerization of the monomer, whereupon the excess non-hardened photoinitiator and non-pulverizable monomer is removed.

Abstract: The lens comprises diffracting components, the contour of which is delimited by non-degenerate centred conic sections. More precisely, according to the invention, the lens comprises adjacent diffracting components of hyperbolic or elliptical contour whose periodicity in r in two mutually-orthogonal directions X, Y, passing through the axis of the lens and being coincident with the principal axes of the hyperbolae or ellipses is determined respectively by the expressions: DELTA r x = 2 lambda ¦fx¦ , DELTA r y = 2 lambda ¦fy¦ in which: DELTA r x represents the periodicity in r in the direction X, DELTA r y represents the periodicity in r in the direction Y, lambda represents the average wavelength of use, fx represents the desired focal point in the plane X and fy represents the desired focal point in the plane Y. … …
