Traditional electronic endoscope using xenon lamp as light light, this is known as "white" NBI endoscopic imaging  blu-ray is actually made up of R/G/B (red/green/blue) of three kinds of light, the wavelength of 605 nm, 540 nm, 415 nm, respectively. Narrow band cold light imaging narrowband filters instead of traditional broadband filters to limit light of different wavelengths, leaving only red, green and blue narrowband waves of 605nm, 540nm and 415nm. Narrowband cold light source imaging narrow-band light waves penetrate the depth of the gastrointestinal mucosa is different, the blue wavelengths (415 nm) through the shallow, red light (605 nm) can be as deep as submucosa, used to display the submucous vascular network, green wavelengths (540 nm) can well display the middle tier of blood vessels. Due to the optical properties of the blood in mucous membrane of blue and green light absorption is stronger, so it is difficult to spread and can be absorbed by the blood of the light, can increase the contrast of the mucosal epithelium and submucosal vessels and clarity. Therefore, NBI has the effect of mucous membrane staining. It is called electronic staining endoscope because it can be applied without spraying stain by pressing the button.
   Hello, SunnerLED company focus on the special LED design and application, on the medical market and special lighting.

Autologous fluorescence imaging can detect small changes in tissue by causing long wavelength fluorescence emission by special short wavelength long light. The most common target is collagen. The autofluorescence system found that the abnormal gastrointestinal performance mostly depended on the absence of collagen in the abnormal hyperplasia tissues, resulting in the reduction of green fluorescence and the enhancement of red fluorescence. But the AFI deficiency existing image resolution, and high false positive rate and NBI endoscopic imaging  blu-ray endoscopy, virtual staining endoscopy to form the so-called triple imaging mode can enhance its specificity. Sanlian imaging mode observer can use AFI advantages discovered gastrointestinal lesions with red fluorescence, Narrow band cold light imaging and then through a narrow cold light imaging hd and virtual endoscopy staining endoscopy further observe its surface features.
