Description

Technical field

[0001] The invention belongs to the technical field of photoelectric spectrum detection and spectrum biochemical analysis; in particular, it relates to the structural design of a spectrum detection biochemical analyzer. Background technique

[0002] Ordinary biochemical analyzers and spectrophotometers similar to instruments have only one monochromator system, and some systems have two sets of monochromators, but the detector is shared by two channels and does not have the performance of a linear array detector.

[0003] A dual spectrometer system (USP5,793,486) as a color sensor is used as a paper color measurement instrument. The system uses two spectrometers. One is aimed at the high reflection area (white area) of the paper, and the other is aimed at the high absorption area (black area) of the paper. Two spectrometers measure the full spectrum of the two regions at the same time. This system is suitable for online measurement of the color and color-related ch...
