Spectrometer SM-9000

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.
