PHOTOELECTRON MULTIPLICATION SYSTEM AND MICROSCOPE

摘要

PROBLEM TO BE SOLVED: To provide a photoelectron multiplication system that is so structured as to be able to measure even an extremely weak optical signal with a structurally simple means; and to provide a microscope having the system. SOLUTION: This photoelectron multiplication system including a detection tube, and an acceleration voltage supply unit for supplying an acceleration voltage necessary for operating the detection tube is characterized by arranging the detection tube 1 and the acceleration voltage supply unit 2 on the sides different from each other of a thermal separation element 3.
