About BLI

General Information about BLI

Blue Light Imaging (BLI) concentrates and intensifies specific wave lengths of light, resulting in a better visualisation of the superficial microvessel and mucosal surface structures to enhance the subtle contrast of the irregularities of the mucosa.
For a safe diagnostic and therapeutic procedure.

The new definition of light 4-led multi light™ technology

Optimal Illumination using variable LED light intensity

Achieving optimal diagnostic and therapeutic results in endoscopic procedures is highly dependent on image quality. Therefore the 4-LED Multi light technology was developed providing the observation mode BLI.



  • A high performance spectrum of light is generated from a powerful light source with four individual LED light bulbs.
  • Enhanced visualisation of haemoglobin, and thus blood vessels, is generated by the high peak intensity of short-wavelength light (blue-violet and blue).
  • Specific light spectrum settings targeting the mucosal layers result in improved contrast and higher definition of imaging.

Unique multi light™ technology for excellent visualisation


Optimal light configuration of four LEDs

With the involvement of numerous clinical experts the ideal composition of four LEDs has been developed to achieve the optimal results in illumination.

White Light Mode

BLI Mode


White light mode

The white light mode provides superior image quality in terms of sharpness and brightness to gather optimal visual information for diagnostic and therapeutic procedures in daily clinical practice.


BLI (blue light imaging) mode

High-intensity contrast imaging with BLI allows superior visualisation of superficial vascular and mucosal patterns. Focussing on the characteristics of short wavelength absorption of haemoglobin (at 410 nm) combined with specific white light spectral
colours results in improved and accurate contrast imaging.
