Spectrometer SM 9000
Quick, reliable and easy measurements in the field or laboratory
About...

Spectrometer SM 9000 is used for high-resolution and high-sensitivity measurements in fibre optic spectroscopy applications. It covers UV/VIS or NIR spectral range. SM 9000 can be used as a stand-alone instrument or as a optional enhancement of other PSI instruments for precise analysis of the spectral curves (in irradiance, absorption, emission mode).

Key Features

  • Very high sensitivity and thermal stability
  • Suitable for microspectrophotometry
  • Sensors individually spectrally calibrated with Hg-Ar-lamp for high accuracy measurements
  • Dark signal subtraction
  • Robust and modular design


  • Very low temperature – induced drift
  • Multicolor LED light source as optional accessory
  • Spectrum v. 2.0 software for spectra presentation and acquisition control
  • Variable exposure time, from 3 milliseconds to minutes.
  • Connection with PSI FluorCams and Fluorometers for synchronization of measured spectra with light flashes

Spectrometer SM 9000


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