Grating scanning near infrared spectrometer
Model：SGS1900
Overview
Sgs1900 series near-infrared spectrometer adopts a grating scanning system for light splitting by driving micro scanner device at high speed, which can measure the spectral measurement up to 1900nm (sgs-1900) wavelength that cannot be covered by the previous small near-infrared spectrometer. High sensitivity, high-speed measurement and computer remote operation. It is suitable for embedded applications of industrial equipment (online detection). With the successful application of grating scanning system, the detector adopts InGaAs non cooled single element (InGaAs array detector has the problems of low yield and high price), which has the characteristics of high cost performance and compact design. It is fast and can specify multiple constituent substances, which is suitable for on-line detection. It can also be used in the field of quality management of organic sampling equipment.Description
