Spectrometer SM-9000
The SM-9000 spectrometer is used for high-resolution, high-sensitivity measurements in fiber optic spectroscopy applications. Covers UV / VIS or NIR spectral range. The SM 9000 can be used as a standalone instrument or as an optional upgrade to other PSI instruments for precise analysis of spectral curves (in irradiance, absorption, emission mode).
The very high sensitivity and thermal stability of the instrument allows single cell fluorescence emission spectra to be measured when combined with our µ-FluorCam device. Spectra can be measured in the range of UV (200 nm) to NIR (980 nm) with a resolution of 3.5 nm (FWHM). Fast recording can capture up to 300 spectra per second (external trigger input) with 16-bit data resolution.
