SGS 1900 - Scanning Grating (Micro)Spectrometer

Scanning Grating Spectrometer

CTR’s Grating Spectrometer operates according to the Czerny-Turner monochromator principle. Classical instruments typically employ a large gratingwith stepper motors and associated bulky mechanical devices. Instead, a micro scanning reflector - developed by IPMS – equipped with a reflective diffraction grating is utilised here.

A miniaturised grating spectrometer with a scanning grating offers the possibility to use special detectors (single element) which show either specific spectral properties e.g. for NIR or extremely high sensitivities (cooled detectors or photomultipler). Especially the NIR can be made accessibly to the segment of compact low-cost systems for the first time.

The spectral components of the incident light arescanned across an exit slit by the tilting movement of the grating. Electrostaticly driven the grating achieves tilting angles of up to ±11° at several hundred oscillations per second in which a complete spectrum can be collected within one oscillation pass. With the presently used components the wavelength range between 1200 – 1900 nm can be covered in one scan.

The system described here possesses a single processor (DSP) based controller and signal processing unit as well as an integrated USB interface and is available as an evaluation-kit. A future realisation in machtbox size is achievable. The technology has been licensed and launched successfully by HiperScan.

SGS 1900 is distributed by the German company HiperScan.
