Handheld 2D High Frequency Surface Scanning Raman Spectrometer - China Suppliers and Factory Solutions

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.

  The Raman rapid analysis model based on deep learning is established, through data training, self-learning and parameter optimization.

Due to its surface scanning ability, it's perfect for field detection of explosives, drugs, dark materials, component analyzing for border, customs, airports, army, food and pharmacy plants, oil plants, emergency organization and food medicine supervision departments.

• Q

  What is the spectral range and resolution of this handheld Raman spectrometer?
  The spectral range covers 200–2800 cm⁻¹ with a resolution of 8–11 cm⁻¹. The laser wavelength is 785 nm ± 0.02nm, and the laser power is continuously adjustable from 1 to 500 mW, allowing flexible adaptation to different sample types and detection requirements.
• Q

  Can this Raman spectrometer safely detect dark-colored or energetic substances?
  Yes. The high-frequency surface scanning mode powered by MEMS technology moves the laser dynamically across the surface rather than concentrating on a fixed point, eliminating the risk of ignition or sample damage. Dark-colored flammable substances such as potassium permanganate — which conventional Raman devices cannot safely handle — can be reliably detected in this mode.
• Q

  How long does the battery last and how is the device powered?
  The device operates continuously for a minimum of 8 hours on a single charge of its rechargeable 18650 lithium battery, performing at least 25 measurements per hour (verified using ethanol at analytical purity), meeting the demands of extended field operations.
• Q

  What packaging or container materials can this device analyze non-invasively?
  The device supports through-barrier penetration detection of substances inside white paper, envelopes, plastic bottles, brown glass bottles, and other micro-transparent materials, enabling safe and non-destructive identification without opening or compromising the container.
• Q

  What industries and field applications is this device designed for?
  It is designed for a broad range of applications including on-site detection of explosives, drugs, and dark-colored materials, as well as chemical component analysis for border control, customs, airports, military units, food and pharmaceutical manufacturing, oil plants, emergency response organizations, and food and medicine regulatory authorities.
• Q

  What is the IP protection rating and operating temperature range?
  The device carries an IP67 protection rating, providing complete dust-tight protection and resistance to temporary water immersion. It operates reliably across a temperature range of -20°C to 50°C, making it well-suited for harsh field environments and extreme climate conditions.
