Brief introduction:
NIR series fiber optic spectrometer (also known as portable spectrometer/micro spectrometer) is a high-performance, low electronic noise, the light of the good response and stable performance. Due to choose the high quality of long wave line type thermoelectric refrigeration InGaAs detector, NIR can cover the 900-2500 - nm wide spectrum, is that you do moisture detection, chemical composition analysis, laser and optical characterization applications such as the best choice. Features:
Long wave InGaAs detector technology
Use Japan marina pine high quality long wave type was InGaAs detector, with low noise, low dark current, nearly infrared wavelengths expand to 2500 nm
The thermoelectric refrigeration technology
Through integrated thermoelectric refrigerator inside the CCD chip, can degrade the CCD chip temperature more precisely. Complex of the laboratory level products are used in refrigeration technology reduce the dark current noise of the spectrometer, extend the integration time
High resolution technology
Using high resolution optical platform based on PG, with 100 mm focal length, at the same time using symmetric C - T light path, eliminating aberration, improve spectral resolution effectively

NIR series near-infrared optical fiber spectrometer is a linear array near-infrared spectrometer with thermoelectric internal cooling technology. A high-resolution optical platform is used. The linear array InGaAs CCD greatly improves the spectral acquisition of the spectrometer. The fastest integration time of the spectrometer can reach 1 ms and the spectral detection range can reach 900 ~ 2500nm. NIR series near-infrared fiber spectrometers are especially suitable for occasions that require fast spectral analysis in the near-infrared spectrum, and are widely used in the fields of moisture detection, chemical composition analysis, laser characterization and fiber characterization.
