By using dedicated filters to filter out broadband light waves, only leaving blue and green light waves with wavelengths of 440nm and 540nm. Since the fibrous tissue of the mucosal layer readily absorbs light waves with a wavelength of 440nm, while light waves with a wavelength of 540nm act on the submucosal vessels, utilizing their spectral characteristics can increase the contrast and clarity of the mucosal epithelium and submucosal vessels, thereby improving the accuracy of endoscopic diagnosis.
