Welcome to Stellenbosch University

Vibrational Spectroscopy Unit

The unit which is located in the Food Sciences Department is equipped with two systems; a Visible Near Infrared (VNIR) and Short Wave Infrared (SWIR) imaging system operating in the 400 – 1000 nm and the 950 – 2500 nm spectral range, respectively.  Users have the option to image samples in the reflectance or transmission mode.  Each set-up have its own LabRack with sample moving stage.  A variety of lenses are also available for use.   Four dedicated computers with the Evince and Breeze software is available for acquiring images and for data analysis and processing.

Clients from both academia and industry are welcome to make use of the available equipment in this unit.

Equipment available in the unit

  • The unit houses the following instruments:
  • HySpex VNIR-1800 for reflectance imaging
  • HySpex SWIR-384 for reflectance imaging
  • HySpex dual VNIR/SWIR for transmission imaging
  • VNIR 30 cm, 1 m and microscope lens
  • SWIR 30 cm, 1 m and microscope lens
  • Breeze and Evince software (Prediktera) for capturing images and chemometric data analysis
