Description

technical field [0001] The invention belongs to the field of experimental detection, and in particular relates to an automatic observation device for mineral spectrum detection, which is used to realize fixed and automatic observation of mineral samples. Background technique [0002] At present, in mineralogy, the selective absorption of full-spectrum visible light by different mineral samples is often used as an important feature for mineral identification and identification. There are generally two known methods for spectroscopic detection of mineral samples: the most commonly used is the transmitted light detection method, the full-spectrum visible light directly penetrates through the mineral sample to be tested and enters the spectroscope, and the transmission spectrum can be observed; the other method It is a reflected light detection method. The full-spectrum visible light is reflected and refracted in the mineral sample to be tested, and then enters the spectroscope....

AI Technical Summary

Problems solved by technology

This method is not only inefficient and highly dependent on the experience and proficiency of the inspector, but also has many problems:

[0003] (1) The light source used is a high-power fiber optic lamp, which consumes a lot of power and has a complex structure. The fiber optic hose is very easy to damage, and the high temperature generated by long-term work will destroy mineral samples;

[0004] (2) When holding a mineral sample with a small size, a small amount of light will enter the spectroscope through the finger, and the spectrum of human blood will be mixed into the observed spectrum, which will bring great errors to the test results;

[0005] (3) The observation space is not airtight, and some stray light is directly injected into the observation hole of the spectroscope, reducing the observed spectral resolution;

[0006] (4) The observation results in the spectroscope eyepiece cannot be archived;

[0007] (5) The transmission spectrum and reflection spectrum of the same sample cannot be compared

This utility model is only suitable for transmitted light observation, and cannot be used in reflected light observation method, and the fiber optic lamp will easily damage the mineral samples to be tested due to long-term work and heat, and the observation results cannot be preserved.

[0009] To sum up, in the prior art, the mineral spectrum detection operation is complicated, and the detection equipment used is easily damaged; the high temperature generated during the operation of the equipment not only generates huge energy consumption, but also easily causes damage to mineral samples, which is contrary to the "non-destructive The basic principle of "detection"; the detection process is greatly affected by the external environment, resulting in large errors in the detection results, low resolution, and cannot be archived, let alone the results obtained by the two detection methods of transmission and reflection can not be accurately compared and analyzed

The existence of the above problems directly reduces the work efficiency of mineral spectrum detection and the accuracy of detection results
