Abstract
PURPOSE: To cover for shortage of dynamic range in a thermo-luminescence measuring apparatus using photon calculation method, by providing specific optical filters in each optical path.
CONSTITUTION: Thermo-luminescence emitted from a thermo-luminescence element 2 heated by a heating device 1 is cut off in the vicinity of the wavelength thereof to be rid of long wavelength component by optical filters 3a, 3b of which transmissivity ratio is about 102, and enters photoelectric multipliers 4a, 3b which are connected to high voltage power source 8. Each output is amplified by high speed pulse amplifiers 5a, 5b, and signals of excellent S/N will be obtained from discriminators 6a, 6b. The output pulses therefrom are counted for a certain time in pulse counters 7a, 7b. In b-system in which light of 1/100 intensity of a-system enters, when the results of counting by counter 7b exceeds 104, it is detected by a comparator 9, and the connection is changed from a-system to b-system by a multiplexer 10, and the result is displayed in the display unit 11.
