iSPEX has many possibilities for educational projects where mobile phones can be used for education for once in stead of them being a general nuisance. Some example projects are:

  • With just the spectral (colour separating) properties of iSPEX even the youngest children can look at the different ways lamps create light. Light from a fluorescent light has a totally different spectrum from a normal lightbulb, even though they both appear to be white.
  • With iSPEX it is possible to measure polarisation of all sorts of objects to see their properties. Young teens can look at the different refraction properties of blue sky and clouds and understand why the sky is blue and clouds are white. They can also look at different polarisation effects in their surroundings, such as in windows, computer screens and 3D glasses.
  • For physics and chemistry students in the higher classes iSPEX can be used for experiments where they have to measure the concentration of sugar in their soda by looking at the degree of polarisation.
  • Spectroscopy and polarimetry are both techniques often used in Dutch astronomy and space research. The most striking example is the hunt for earthlike planets at other stars.
