Endoscope light source

ALI Lum-C1

Endoscope light source of very high intensity. It provides the light flux of intensity required for recording the vocal folds function by a high-speed camera.

ALI Lum-C1 – illuminator

An innovative device with unique features:

  • does not cause overheating of endoscope optics – the advanced optical system and the use of laser emitters provide highest efficiency and eliminate the excessive heat production which is typical for classic high-intensity light sources;
  • the lightweight and compact illuminator head mounted directly to the endoscope makes the examination with the high-speed camera to be performed without effort and as easy as an ordinary videostroboscopic examination;
  • excellent visualization of blood vessels, the edges of vocal folds and irritated mucosa thanks to originally chosen spectral characteristics (colour) of the emitted light;
  • maximum image sharpness in the ALI Cam HS-1 camera thanks to optimally chosen light parameters;
  • fully automated operation thanks to control of illuminator functions by the software from the computer managing the examination, according to the selected mode of camera operation – besides switching the device on, there is no need to adjust any controls in the front panel;
  • long lifetime of the illuminator head and quiet operation, important while performing phoniatric examinations.
