Problems solved by technology
However, most of these infrared instruments use continuous-spectrum light sources. After the continuous spectrum is separated by various spectroscopic devices, it interacts with the substance to be measured, or the recombined light that interacts with the substance to be measured is re-splittered. There is an optical path. Complicated, cumbersome instrument debugging process, expensive and other characteristics, it is difficult to promote and apply in large quantities
[0004] At the same time, due to the high price of existing infrared analysis instruments, many students do not have the opportunity to do it by themselves, and it is difficult to understand the basic methods and techniques used in infrared light applications.

Embodiment Construction
[0014] In conjunction with the accompanying drawings, the working and implementation of a multifunctional laser moisture measuring device will be described in detail below.
[0015] The light collection ball of the present invention adopts diffuse illumination to receive light in the direction of 8° for measurement, and the light collection ball scatteres the light evenly inside the collection ball after multiple reflections, making it an ideal and uniform light source, which has nearly 99% infrared light. % reflectivity, the infrared detector is placed horizontally on the left side of the center line of the light-collecting spherical shell, and a light-blocking baffle is arranged below it to avoid the light reflection of the measured material from directly entering the detector.
[0016] The main part of the light-collecting sphere adopted by the present invention is a hollow complete spherical shell, a measuring box for adorned detection substance is arranged at the directly ...
