Abstract
An optical device for examining a fluid including a measuring space including a compulsory passage for the fluid to be examined, at least one source delivering a selected light to an optical illuminator serving to collect at least part of the light having traversed the compulsory passage and to deliver the selected light to analyze the collected light so as to deliver signals representing data borne by the collected light. The optical illuminator includes a first light guide including one end, opposite the source, and configured to deliver the light, derived from the source, in accordance with a selected geometry to illuminate the compulsory passage in a substantially uniform manner and under a substantially constant intensity.
