Abstract

A method for joining aligned discrete optical elements by which the optical elements can be joined in the aligned state. A thermal connection having long-term stability can be produced at little expense and with high positioning accuracy. Surface regions to be joined can be provided with at least one thin metallic layer by the method for joining aligned discrete optical elements. The surface regions are subsequently wetted using a liquid solder free of flux in a contactless dosed manner. The solder is applied to the surface regions to be joined via a nozzle using a pressurized gas stream.
