The endoscope system is known to include a light source machine and an endoscope, wherein the endoscope is used to detect the object to be measured, and the light source is used to provide a white light source required for the endoscope to detect the object to be measured.

However, when the white light source is used to detect the object to be measured, only the surface of the object to be tested to be tested can be detected, and the image of the surface to be tested to be inspected cannot be detected, so that the user can manipulate the endoscope. When the object to be tested is detected, only the change of the physical appearance of the position to be tested of the object to be tested can be determined, and other conditions of the position to be tested of the object to be tested cannot be detected at the same time.

Therefore, there are further manufacturers that manufacture a light source that filters the light source by means of a filter, so that the light source machine can generate light sources of different spectra, so that the endoscope can detect the object to be measured by various light sources of different spectra, wherein the object to be tested is to be tested.
