[0024] Example: such as figure 1 As shown, firstly, the laser light from the external laser 1 is extracted from the optical fiber, and then introduced into the confocal scanning module 3 through the collimator 2 . The confocal scanning module includes a dichroic mirror 4 (transmitting long wavelengths and reflecting short wavelengths) and two scanning galvanometers 5 whose rotation axes are perpendicular to each other. The dichroic mirror reflects the excitation light to the scanning galvanometer, which passes through Two reflections allow the excitation light to travel downwards. Afterwards, the excitation beam passes through the Scan lens 6 and the Tube lens 8 in the trinocular lens 7 in sequence, and then is expanded, and the expanded parallel light is focused into a point by the objective lens 9 to excite the probe. The generated fluorescence signal is collected by the objective lens, returns to the original path through the above optical path, and passes through the dich...
