A brief introduction: Portman portable Raman spectrometer is a small Raman spectrometer designed for various scenarios such as laboratory and on-site testing. The device host can configure different excitation wavelengths, spectral ranges, and resolutions according to customer needs and applications. The high-performance array back illuminated detector with a minimum temperature of -25 ° C provides customers with high-quality Raman spectroscopy signals. Laser devices that meet the IIIB laser safety level requirements can be controlled and set by software, providing customers with a one click data acquisition experience. Diversified sampling accessories meet customers' measurement requirements for samples of different shapes such as solids, liquids, powders, etc. Targeted micro area sampling accessories and immersion probes can achieve various complex scenarios such as SERS, 2D materials, jewelry, online chemical engineering, biomedicine, and pharmaceuticals. Software configuration includes functions such as Raman spectroscopy for fluorescence removal, signal extraction, recognition, and database management. Portman has been widely used in industries such as food safety, national defense security, jewelry appraisal, medicine, etc. that require rapid screening of raw materials, on-site rapid testing, and substance analysis appraisal.
