Abstract

A method of producing an infrared lamp for a vehicle night vision system, where the lamp has a tube which surrounds a radiation source that emits infrared radiation and light radiation. The tube has an infrared-transmitting coating. By setting specific process parameters in the coating process and/or by post-treating the coated tube, holes are formed in an irregular arrangement in the coating. The holes have at least in some areas a defined average size and a defined average surface density.
