ABSTRACT:
A method manufactures a digital image sensor including at least one optical lens using a hardenable liquid or gelatinous material. The method includes depositing a calibrated volume of the material on a lens formation base using a tubular needle of a small diameter, so that the volume of material deposited has at least one convex part under the effect of interface energies, and hardening all or part of the volume of deposited material.
