SYSTEM AND METHOD FOR SIMULTANEOUSLY PERFORMING MULTIPLE OPTICAL ANALYSES OF LIQUIDS AND PARTICLES IN A FLUID

摘要

An immersion probe system is provided for simultaneously performing first analysis of a first portion of light originating from liquids and/or particles in a fluid and second analysis of a second portion of the light originating from the liquids and/or particles. The system defines an optical axis and includes a first component including a first analyzer, a window, and a first optical path extending between the window and the first analyzer. The system also includes a second component including a second analyzer, the window, and a second optical path extending between the window and the second analyzer. The system further includes a spectral selector placed in the first optical path and in the second optical path to direct the first portion of the light, which originates from the liquids and/or particles and passes through the window, to the first analyzer, and to direct the second portion of said light to the second analyzer. The system includes an illumination path that delivers illumination light or lights based on a beam(s) that passes through the window at an oblique or normal angle to the optical axis. The first component and the second component share a common optical path at least between the window and the spectral selector.

1. A system for simultaneously performing first analysis of a first portion of light originating from liquids and/or particles in a fluid and second analysis of a second portion of the light originating from the liquids and/or particles, the system defining an optical axis and comprising:
a first component including a first analyzer, a window, and a first optical path extending between the window and the first analyzer; a second component including a second analyzer, the window, and a second optical path extending between the window and the second analyzer; a spectral selector placed in the first optical path and in the second optical path to direct the first portion of the light, which originates from the liquids and/or particles and passes through the window, to the first analyzer, and to direct the second portion of said light to the second analyzer; and a fluid-immersible probe, the probe including the window at its distal end, the probe further including an illumination path that delivers illumination light or lights based on a beam(s) that passes through the window at an oblique or normal angle to the optical axis; wherein a portion of the first optical path between the window and the spectral selector coincides with a portion of the second optical path between the window and the spectral selector such that the first component and the second component share a common optical path at least between the window and the spectral selector.
