ABSTRACT:
Method and device for producing lenses of microoptical systems and an optical emitter/receiver system. A curable liquid lens material is introduced into a mount which serves as a lens holder for the lens to be produced, and a convex lens surface is formed at an opening of the mount. The lens material introduced into the mount is irradiated with light during its introduction. An optoelement which forms part of the microoptical system is arranged relative to the lens at a position which it shall assume in the completed microoptical system. Simultaneously with the introduction process, either the image of a light emitter as the optoelement is measured in a selected plane at the side of the mount opposite the optoelement, or the signal intensity of the signal which is changed in an optical sensor as the optoelement as a result of incident light, and the introduction process is terminated when the image or the signal has reached a predetermined size and/or shape.
