Embodiment 1

[0028] A Raman spectroscopy probe extension device for detecting deeper solid samples. Its structure is as follows figure 1 As shown, it includes: an inner tube 6, a window 3 is opened on the side wall, a reflector 5 located in the inner tube 6, a window protection sleeve 2 sleeved outside the inner tube 6, and a pointed cone arranged at the front end of the inner tube 6 Body 4, and a focusing lens 1 provided at the rear end of the inner tube 6.

[0029] Quartz glass is embedded in the window 3 to increase the transmittance of Raman reflected light. The window 3 is arranged at a position close to the pointed cone at the front end.

[0030] The reflecting mirror 5 is placed in the inner tube 6 at 45°, and the reflecting surface faces the window and 3 focusing lens. The window protection sleeve 2 is a retractable structure, which opens and closes the window on the inner tube, so as to avoid the friction of the quartz window when inserting the sample, that is, it is convenient to op...

Embodiment 2

[0045] A Raman spectroscopy probe extension device for detecting deeper solid samples, comprising: an inner tube, a window is opened on the side wall, a reflector located in the inner tube, a window protection sleeve sleeved outside the inner tube, and A pointed cone at the front end of the inner tube, and a focusing lens set at the rear end of the inner tube.

[0046] Quartz glass is embedded in the window to increase the transmittance of Raman reflected light. The window is set at the front end close to the pointed cone. The reflecting mirror is placed in the inner tube at 40°, and the reflecting surface faces the window and the focusing lens. The window protection sleeve is a retractable structure, which opens and closes the window on the inner tube, so that it can avoid the friction of the quartz window when inserting the sample, that is, it is convenient to operate and can protect the quartz glass window. The sharp cone is inserted into the middle of the sample to be teste...

Embodiment 3

[0048] A Raman spectroscopy probe extension device for detecting deeper solid samples. The structure is roughly the same as that of Embodiment 2, except that the reflector is placed in the inner tube at 60°, and the reflective surface faces the window and the focusing lens.

Abstract

The invention relates to a Raman spectrum probe extending device for detecting a deeper solid sample. The Raman spectrum probe extending device comprises an inner tube, a reflecting mirror, a window protective casing, a taper and a focusing lens, wherein a window is formed in the side wall of the inner tube; the reflecting mirror is located in the inner tube; the window protective casing sleeves the inner tube; the taper is arranged at the front end of the inner tube; the focusing lens is arranged at the rear end of the inner tube. Compared with the prior art, the Raman spectrum probe extending device disclosed by the invention has the advantages that convenience in operation is realized, i.e., the probe extending device can be directly inserted into the middle part of a sample bag to acquire Raman spectrum information of the sample; the structure is simple; an optical system consists of the quartz glass window, the reflecting mirror and the focusing lens; a spectrum signal of the sample can be directly reflected into a detector; measurement efficiency is high; after the probe extending device is connected with a Raman spectrum system, the whole spectrum acquisition and matching identification process can be finished in a short time.

Description

Technical field [0001] The invention relates to a detection device, in particular to a Raman spectroscopy probe extension device used for detecting deeper solid samples. Background technique [0002] Because hazardous chemicals are complex and diverse, including gas, solid, liquid, organic volatiles, aqueous solutions, etc., especially in chemical production, unknown chemicals and unknown components may appear. Qualitative analysis can determine the name and type of chemicals. In order to provide information for the follow-up rescue work, which can well respond to chemical emergencies. [0003] Raman spectroscopy has the following features: (1) The light source adopts a laser. Due to the good monochromaticity of the laser, the laser Raman spectrum has sharp peaks and high resolution. (2) Raman spectroscopy sample preparation is simple and does not damage the sample. For solid samples, it can be measured directly by a solid holder, liquid samples can be measured in a cuvette, and s...
