PCT No. PCT/SE86/00325 Sec. 371 Date Jan. 28, 1987 Sec. 102(e) Date Jan. 28, 1987 PCT Filed Jul. 4, 1986 PCT Pub. No. WO87/00271 PCT Pub. Date Jan. 15, 1987.In an instrument for the detection of ultra-violet radiation, visible light or infrared radiation an electric coupling is known, which comprises a photo-diode of silicon or germanium, a measurement resistor, over which generated photo-electric current generates a voltage, and a voltmeter with low leakage current for measuring the voltage generated. For rendering possible a less expensive, simpler and safer structural design than the designs known and commercially available, it is proposed that the measurement resistor RA and the calibrated voltmeter V each are connected in parallel over the photo-diode. |
