PURPOSE:To increase gain of amplification circuit and decrease effect of noise by forming a photoelectric conversion device by combining a photoelectric conversion unit and an arithmetic amplification circuit in a vacuum glass tube. CONSTITUTION:A photoelectric conversion device is formed by accommodating a photoelectric conversion unit comprising a photoelectric cathode 2 and an anode 1 and an arithmetic amplification circuit comprising an arithmetic amplification unit 3, a feedback resistance 4, and a load resistance 5 into a vacuum glass tube 10. Since the photoelectric conversion unit 1 and 2, and the arithmetic amplification circuit 3-5 are closely arranged in the vacuum tube, leak current caused by humidity and effect of noise from the outside are reduced and gain of amplification circuit are increased to obtain steady amplification. Therefore, high sensitive photoelectric conversion device can be obtained. |
