Integrating sphere

Two measurement setups

In the laboratory two permanent integrating sphere setups are available. A small sphere (diameter 15 cm) which is used for spectral reflectance and transmittance measurements in the 8/d measurement geometry and a large sphere (diameter 50 cm) for spectral radiant flux and efficacy measurements of light sources.

Large sphere

A third integrating sphere is available (donated by A. Devogelaere, former lecturer). This setup is only used for demonstration purposes.
