PCT No. PCT/NL94/00227 Sec. 371 Date Oct. 15, 1996 Sec. 102(e) Date Oct. 15, 1996 PCT Filed Sep. 16, 1994 PCT Pub. No. WO95/08109 PCT Pub. Date Mar. 23, 1995A measuring device for measuring the intensity and/or polarization of electromagnetic radiation, more in particular of light. The measuring device is provided with a tunnel tip arranged facing a body at some distance, which tunnel tip at least partly consists of a semiconductor material. The measuring device further comprises a control unit for obtaining information about the intensity and/or polarization of the radiation by means of a tunnel current, generated under the influence of the radiation in the tunnel tip, between the tunnel tip and the body and/or a surface photovoltage of the tunnel tip, generated under the influence of the radiation.
