Overview
1. Transient 0.1 ms Spectral Acquisition: The IR series near-infrared fiber spectrometer uses Hamamatsu arrayed InGaAs detectors, which are different from traditional scanning spectrometers. It can collect spectra at the millisecond level and is very suitable for quickly completing experimental ideas in the laboratory; The $n2 900~2500nm wide spectrum IR series spectrometer covers multiple detection bands in the near-infrared region, providing multiple bands such as 900-1700nm, 900-2200nm, 900-2500nm, etc., to meet diverse sensitivity and band requirements
Product Details

IR seriesNear infrared fiber spectrometerHas the following significant characteristics:

1 Transient 0.1 ms spectral acquisitionThe IR series near-infrared spectrometer adopts Hamamatsu arrayed InGaAs detector, which is different from traditional scanning spectrometers. It can collect spectra at the millisecond level and is very suitable for quickly completing experimental ideas in the laboratory;

2 900~2500nm wide spectrumThe IR series spectrometer covers multiple detection bands in the near-infrared region, providing multiple bands such as 900-1700nm, 900-2200nm, 900-2500nm, etc., to meet diverse sensitivity and band requirements;

3 Deep TEC refrigerationThe IR series near-infrared spectrometer adopts chip level internal cooling technology to deeply cool the InGaAs detector and effectively solve the problem of low-temperature condensation, increasing the signal-to-noise ratio to 5500:1 level;

The 4 IR series near-infrared spectrometer has 256 pixel and 512 pixel detectors to choose from, with higher pixel resolution.

The cooling temperature can reach -20 ℃. Has good spectral response stability and reproducibility, suitable for laser measurement and near-infrared measurement. It is a high-performance fiber optic spectrometer for scientific research and development.

Near infrared fiber spectrometerTypical application areas:

Due to the diversity of samples and the complexity of testing conditions, spectrometers need to have strong system universality and adaptability for transmission, reflection, and absorption spectroscopy.

Online component analysis, such as moisture analysis in tobacco, requires a spectrometer with MS level spectral acquisition and transmission capabilities; At the same time, near-infrared spectrometers need to have chip level internal cooling capabilities to meet stability requirements.

1064nm Raman spectroscopy, film thickness, food, pharmaceutical, environmental, and biochemical detection applications.
