DEVICE FOR MICROBIOLOGICAL ANALYSIS

摘要

PROBLEM TO BE SOLVED: To provide a device for the microbiological analysis of a support adapted to contain microorganisms marked by a phosphor matter, which is both more economical and simpler while being satisfactory in performance. SOLUTION: The phosphor matter is adapted to absorb light energy with an absorption spectrum (53) having a crest (53') at a predetermined absorption wavelength (λ2) and to release energy by emitting light with an emission spectrum (54) having a crest (54') at a predetermined emission wavelength (λ3) distinct from the absorption wavelength (λ2). The device configured to release the energy includes illuminating means, and the spectrum (55) of the excitation light coming from the illuminating means having a crest (55') at a predetermined excitation wavelength (λ1) with a predetermined difference between the excitation wavelength (λ1) and absorption wavelength (λ2) by virtue of which it is made easy to discriminate the light emitted by the phosphor matter from light coming from the illuminating means.
