Handheld Chemical Substance Analyzer
01
Handheld 2 Dimensional High Frequency Surface Scanning Raman
Product Introduction
The handheld high-frequency surface swept Raman spectrometer adopts transmission body phase grating (VPG), spatial direct coupling and confocal technology to realize small volume and large flux Raman signal acquisition, and the sensitivity is 10 times that of traditional Raman equipment. At the same time, digital microscopy technology is used to make the laser no longer gather at a fixed point, but constantly move according to the pre-defined trajectory, which breakthrough solves the technical problems such as excessive focus energy, easy damage and even ignition, and expands the application field of Raman technology. The surface scanning technology in the controllable area can measure the average spectrum of the whole surface, and solves the problem of mixture measurement deviation and suspicious object leakage detection. In this mode, the enhanced detection of more than 10 mixtures can be realized, and the surface contamination distribution of chemical poisons or explosives can be more accurately analyzed. The total amount of material spectrum database is more than 10000, and can be expanded according to the needs to meet the requirements of users.
Features
1. Using the transmission body phase grating technology, the transmission optical path system is used to replace the original reflection structure, and the space direct space coupling is combined to replace the optical fiber coupling to improve the optical collection efficiency, and improve the detection speed and detection limit.
2. The innovative use of micro electromechanical systems in optical systems enables Raman spectrometers with different scanning modes. The high frequency facial mode not only enables the Raman spectrometer to be applied to the detection of dark energetic substances, but also can image the detected objects, which has brought a major breakthrough for the development of Raman detection technology.
3. The Raman rapid analysis model based on deep learning is established, through data training, self-learning and parameter optimization.
