Spectra from this area are of interest to the fields of physics, engineering and semiconductor physics. These light sources are based either on the heating of a material (bulbs) or on recombination-induced light emission in semiconductors (LEDs).

We have created separate pages for the various light sources in our example spectra.

Spectroscopy on Street Lamps

With the help of the Eureca line scan camera e9u-LSMD-TCD1304-STD, it is possible to record sophisticated measurements with high spectral resolution at relatively low cost for school or practical use. A wide variety of different types of lighting are used for street illumination nowadays, with both gas discharge lamps and LED luminaires being used. With the help of a spectrometer, the different light sources can be conveniently measured and the respective spectra evaluated. [More …]
