Abstract:
1. A detection device which irradiates a test subject with excitation light, and detects fluorescence which is radiated from the test subject, the device comprising: a light receiving unit which receives the fluorescence; means for calculating a light receiving intensity of fluorescence which is received by the light receiving unit while changing a relative position between the light receiving unit and the test subject; and means for specifying an optimal position of the relative position where the light receiving intensity which is calculated by the means for calculating the light receiving intensity becomes a maximum, in which the fluorescence is detected using the optimal position which is specified by the means for specifying, wherein the light receiving unit further receives reflected light which is excitation light reflected from the test subject when the test subject radiates fluorescence, wherein means for calculating half-value width of the reflected light is further included, wherein the half-value width is an index denoting the relative position, and wherein the means for specifying specifies the half-value width of the reflected light of which light receiving intensity of the fluorescence becomes the maximum as the optimal position.
