DETAIL
Portman portable Raman spectrometer is a small Raman spectrometer for laboratory testing, field testing and other scenarios. Its high-performance array backlight detectors (up to -25°C) provide customers with high quality Raman spectral signals.
 

The software for Portman series includes functions of Raman spectrum fluorescence, signal extraction, recognition and database management; and the host device can be configured with different excitation wavelengths, spectral ranges and resolutions according to customer requirements and applications. Besides, the laser which complies with the requirements of grade IIIB can be controlled and set by software, so users can get data easily by using one-click acquisition.
 

We also provide a variety of sampling accessories to measure different types of samples, such as solid, liquid or powder. Collocating with targeted micro-sampling accessories and immersion probes, Portman series can be used for SERS, 2D materials, jewelry, online chemical, biological medicine and pharmaceutical and other complex scenes. On the strength of above features and functions, Portman series would be widely used in food safety, national defense security, jewelry identification, pharmaceutical and other industries requiring rapid screening of raw materials, on-site rapid detection and material analysis identification.

► The above parameters are only for standard specification. The resolution is the standard configuration of the 25 μm slit spectrometer. The sensitivity can be reduced by 10 μm for higher resolution, or the sensitivity can be improved by 50 μm slit.
► Raman spectral resolution is the full spectral resolution. If there are different standards, the resolution index is slightly different from the table parameters. Test method refer to JJF1504-2015 standard requirements.
