Since Bohr discovered the relationship between optical spectra and the structure of atoms, spectrometry has served an important role in physics and chemistry. As spectrometers are expensive and accurate calibration is necessary to achieve high quality spectra, we developed a remote lab for optical spectrometry.

With this tool, students can carry out experiments with real apparatus over the Internet. Users can choose from six standard light bulbs. The light from each bulb is collected with a cosine-corrected fiber optic irradiance probe and analyzed with a spectrometer. This allows for further experiments such as measuring the dependence of spectral irradiance on distance from the bulb, as well as identifying the spatial and spectral features of radiant emittance.
