How Portable Near Infrared Analyzer Work?

Apr. 09, 2018

The portable near-infrared analyzer is involved in the field of food, food composition and content analysis, and solves the problems of weak structure and poor stability of the existing near-infrared analyzer using halogen lamp single detector systems, including the upper computer and the upper electromechanical device. Connected controllers, LED light source groups, amplifiers, and A/D converters that are electrically connected to the controllers, respectively, are disposed at the rear end of the LED light source group to receive narrow-band light beam splitters of the LED light source groups, and are electrically connected to the amplifiers. A first detector for receiving the reflected light of the beam splitter, a sample plate disposed at a rear end of the beam splitter for receiving the transmitted light of the beam splitter, and a second detector electrically connected to the amplifier disposed near the sample plate, the amplifier and the A/D The converter is electrically connected.

The use of narrow-band LED light source groups reduces the requirement for subsequent monochromatic light path systems. The light weight, small size, and low power consumption make it possible to eliminate measurement errors and measure results accurately by comparing spectral data in real time.
