Modular Artificial Solar Source
The spectral distribution of the solar radiation and that of the artificial source are compared in the table below. It will be seen that the similarity is quite good, the radiative power in the range of wavelength 0.4µm < l < 2.2 µm being about 90% for the sun and about 76% for the artificial source.
Technical specifications:- 
Lamps :
•  Number : 6.
•  Type : double envelope halogen.
•  Power : 1000 W each.
•  Voltage : 220/380 V, 50 Hz, 3-phase.
•  Life : 2000 hours.

Mirrors :
•  Shape : parabolic.
•  Material : special surface aluminium.
•  Radiation received by the mirrors is in part diffused and in part reflected to form a beam parallel to the axis of the parabola.
