FLUORESCENT IMAGING DEVICE COMPRISING A TWO-WAVELENGTH VARIABLE LIGHTING POWER LIGHT SOURCE

摘要

The fluorescent imaging device comprises a two-wavelength variable lighting power light source (16), which is ring-shaped and is provided with alternating first and second zones (16a, 16b) for respectively emitting first and second light radiations having different first and second wavelengths, respectively. Each zone (16a, 16b) also comprises a plurality of elementary light sources, which are independently controllable by light-selective control means (20) thereof.
