Compact fibre spectrometers
SGM1700 Cooled NIR Fibre Spectrometer
A complete 900–1700 nm fibre spectrometer with a cooled 512-pixel detector and a 100 mm crossed Czerny–Turner optical bench. Select sensitivity or dynamic-range operation around the sample signal.
Best suited to
Liquid concentration monitoring, NIR material characterisation and industrial integration.
Selecting a configuration
Specify the fibre collection geometry, slit and expected optical power. Cooling stabilises the detector; enclosure temperature and integration time still matter for a repeatable process measurement.
Measurement & configuration
- Detector cooled to −10 °C at 25 °C ambient.
- Software and external trigger modes.
- C++ development support.
