The handheld area-scanning Raman analyzer offers two key advantages. First, a digital micromirror device enables rapid scanning and detection, upgrading conventional fixed-focus measurement (typically using a 50 μm spot diameter) to high-speed area scanning. The side length of the rectangular scan area can be adaptively configured according to operational requirements or sample size. This reduces the risk that focused laser light may ignite or detonate flammable, explosive, or dark-colored chemicals, while also enlarging the sampling area. Second, the analyzer supports point-by-point scanning. By measuring multiple points within a defined sample area, it further improves the detection capability for mixtures.

By combining Raman spectroscopy with high-speed controllable area-scanning technology, the laser is no longer focused on a single fixed point during measurement; instead, it scans along a pre-programmed trajectory.

◆  A rectangular scan area of any size within 3 × 3 mm can be configured, allowing the scan area to match the sample.

◆This helps eliminate the ignition and explosion hazards that may occur when a fixed laser is used to test flammable, explosive, or dark-colored chemicals, while also avoiding molecular damage caused by high-energy laser irradiation.

◆It significantly improves the accuracy of powdered-mixture analysis and greatly reduces missed detections of mixture components.

◆ It enables Raman matrix detection, also known as Raman imaging. Through point-by-point surface scanning, the system can analyze the distribution of surface contamination by toxic agents, flammable and explosive substances, and other toxic or hazardous chemicals with greater precision.
