Fluorescent Imaging Device Comprising a Two-Wavelength Variable Lighting Power Light Source

摘要

A fluorescence imaging device comprises a light source with two wavelengths and variable lighting power. The light source is in the form of a ring and it comprises an alternation of first and second zones respectively able to emit first and second light radiations respectively having distinct first and second wavelengths. Each of the zones further comprises a plurality of elementary light sources controllable independently by selective lighting control means of said elementary sources.
