1. A portable confocal optical scanning microscopic device, which can be modularized to be assembled and disposed on an operating board to perform optical scanning to a test specimen to obtain an image, the device comprising:
an optical path module, comprising a beam splitter and a focusing lens, the beam splitter has a light incident side, a reflective side and a light outlet side, and the focusing lens is located at the reflective side of the beam splitter;
a light source module, comprising a light generator, the light generator is for generating an incident light to be injected into the beam splitter from the light incident side along a first axis;
a light receiving module, comprising a spatial filter; and
an object stage, for setting the test specimen, the object stage is located at a side of the beam splitter opposite to the focusing lens;
the optical scanning is that the incident light is injected into the beam splitter, and penetrated the focusing lens, and then shot to the test specimen, so that the incident light generates a reflected light on the test specimen, after the reflected light is shot back to the beam splitter from the reflective side, the reflected light is shifted to the light outlet side, the reflected light is then shot to the spatial filter to filter the reflected light that is not focused on the test specimen; wherein the optical path module, the light source module, the light receiving module, and the object stage can be disassembled and assembled on the operating board to flexibly configure an adaptive combination capable of performing the optical scanning.
