24-8-1979 1 PHD. 79-033. ABSTRACT: "Method of producing microlenses and a coupling element having a microlens produced in accordance with this method". Microlenses which are easy to handle are produced by providing rotation-symmetrical recesses in a glass plate, depositing vitreous layers by means of a vapour deposition process onto the plate, until the re- cesses are fully filled up, whereafter the thickness of the coated glass plate is reduced to the original value or to a smaller value. Two lenses produced in this manner are then combined to one lens by placing the embedded lenses on top of one another by means of their flat sides.
