A brief introduction: NIRPro is a cooling type near-infrared fiber spectrometer based on symmetrical CT optical path design. It has a compact structural design, configurable spectral range, and adopts N A0.11, High resolution, optimal up to 0.3nm; Low stray light,~0.5 ‰. Equipped with back illuminated and cooled InGaSe detectors, the spectral range can cover multiple standards such as 900nm-1700nm, 900-2200nm, and 900-2500nm depending on the selection. 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.
