Abstract (en)
[origin: EP1376504A1] The device has an optical measurement chamber with a sensor arrangement with a light source(s) and a receiver(s) in their own elongated housings with small window openings and a labyrinth system. The light source(s) and receiver(s) are arranged in the rear parts of their housings so that there is a relatively large distance between the window openings and the optical surfaces of the light source(s) and receiver(s) through which light passes. The device has an optical measurement chamber with a sensor arrangement (2) with at least one light source (12') and receiver (11) in their own housings (13,14) and a labyrinth system (7). The elongated housings have small window openings. The at least one light source and receiver are arranged in the rear parts of their housings so that there is a relatively large distance between the window openings and the optical surfaces of the at least one source and receiver through which light passes.
