PROBLEM TO BE SOLVED: To maintain a displayed image at a constant brightness even when exposure time is altered in photon counting detection.SOLUTION: Provided is an optical detection system 40 comprising: a detector 41 having a light receiving portion 42 configured to receive fluorescence generated from a sample S, then photo-electrically convert the fluorescence received by the light receiving portion 42, and output a current signal of a magnitude corresponding to the quantity of light; a measuring instrument configured to measure the number of photons included in the current signal output from the detector 41; an input section 47 configured to input an actual exposure time for which the fluorescence is exposed in the light receiving portion 42; and a PC 45 configured to compose an image of the sample S on the basis of a luminance value obtained by multiplying the inverse number of the proportion of the actual exposure time input by the input section 47 with respect to a predetermined reference exposure time and the number of the photons measured by the measuring instrument. |
