Spectrophotometric and nephelometric unit detection.

摘要

Device for carrying out optical measurements, of the type containing a first sensor (17), a second sensor (25) and a third sensor (22), suitable sensors to perform the light measurement and a common focus the beam along a beam axis (24) with two power coupled light (1, 2) with different spectral ranges, for performing conduction of light to the desired location in which it is verified the measurement, comprising elements arranged in the priority order indicated: a) at least one beam splitter (5) dichroic, to carry out the combination of the light emerging from the light sources with different spectral ranges b) a bucket (11) as a place in which the c reaction is monitored) at least one diaphragm (13), the diaphragm (13) being shaped annular diaphragm and perforated diaphragm, which passes on the one hand , the scattered light impinging on the diaphragm under a certain range solid angle and, on the other hand, the transmitted light passes, which affects the diaphragm under next small angles 0 °, and wherein the first sensor (17) measures the scattered light, the second sensor (25) measures transmitted light, and the third sensor (22) measures a part of the incident light by reference.
