Abstract
Provided are an optical measuring instrument, a flow cytometer, and a radiation counter which reduces a size and a weight of a photodetector, and enables detection of weak pulsed light with a high degree of accuracy and at a high speed. A laser beam source irradiates a specimen to be measured with a laser beam and generates a light pulse of intensity corresponding to the irradiation. An imaging element provided with a pixel including a photoelectric conversion element and an amplification element which sequentially accumulates charges subjected to photoelectric conversion by the photoelectric conversion element for a predetermined period and outputs a voltage as a pixel signal according to an accumulated charge amount after the accumulation is completed through the amplification element, and detects a light amount of the light pulse on the basis of a pixel signals of a pixel group.
