Abstract
Device and method for producing a plurality of microlenses from a lens material. The method includes: applying lens material intended for the embossing of the microlenses to a plurality of first lens molds distributed on a first embossing side of a first die for embossing of the microlenses, moving the first die and a second die located essentially parallel, in an X-Y plane, and opposite the first die, on top of one another in a Z-direction running essentially perpendicular to the X-Y plane, embossing the microlenses by shaping and curing the lens material, the shaping taking place by moving the first and second embossing sides on top of one another, up to a thickness D1 of the lens material in the Z-direction, wherein the lens material of each microlens at least during curing is separate from the lens material of each microlens which is adjacent in the X-Y plane.
