| 摘要 |
The invention concerns an optical device for examining a fluid (D) comprising a measuring space (4) including a compulsory passage (5) for the fluid to be examined, at least one source (7) delivering a selected light to optical illuminating means (21-25) serving to collect at least part of the light having traversed the compulsory passage (5) and to deliver same to means (20) serving to analyze the collected light so as to deliver signals representing data borne by same. The optical illuminating means (8-12) comprise first light guiding means (8) including one end (9), opposite the source (7), and configured to deliver the light, derived from the source (7), in accordance with a selected geometry so that it illuminates the compulsory passage (5) in a substantially uniform manner and under a substantially constant intensity.
