Handheld 2D High Frequency Surface Scanning Raman Spectrometer - China Suppliers & Factory Best Quality
🔬 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.

❓ Frequently Asked Questions
QWhat makes this handheld Raman spectrometer different from traditional Raman equipment?
This device adopts transmission body phase grating (VPG) technology combined with spatial direct coupling and confocal technology, achieving sensitivity 10 times higher than traditional Raman equipment. Its digital microscopy-based surface scanning ensures the laser continuously moves rather than focusing on a single point, eliminating risks of sample damage or ignition.
QCan this device safely detect dark-colored or energetic materials?
Yes. The high-frequency surface scanning mode allows safe detection of dark-colored flammable substances such as potassium permanganate and other energetic materials. By distributing laser energy across the scanning area instead of a single fixed point, the risk of ignition or sample damage is effectively eliminated.
QWhat types of packaging can the spectrometer detect through?
The device supports non-destructive penetration detection through white paper, envelopes, plastic bottles, brown glass bottles, and other micro-transparent materials, allowing identification of substances without opening or damaging the packaging.
QHow large is the built-in material spectrum database, and can it be expanded?
The built-in spectrum database contains more than 10,000 material entries. It can be expanded as needed to accommodate new or specialized substances, ensuring the system remains adaptable to evolving detection requirements across different industries.
QWhat is the battery life and how is the device powered?
The device is powered by a rechargeable 18650 lithium battery and supports continuous operation for no less than 8 hours, verified using ethanol at a measurement rate of no less than 25 times per hour, making it well-suited for extended field operations.
QWhat environmental conditions can this spectrometer operate in?
The device carries an IP67 protection rating, making it fully dust-tight and waterproof. Its operating temperature range is -20℃ to 50℃, allowing reliable performance in demanding outdoor environments including border checkpoints, field operations, and industrial sites.
