Sun simulator

The sun simulator is a light source that provides a beam of light with a number of characteristics similar to solar characteristics in order to influence the orientation system of the model, as well as the conditions of shooting the globe sections with a camera installed in the satellite model.

Main parameters of the simulator:

  • non-parallelism of the beam is not worse than 12 deg,
  • the radiation spectrum is as close as possible to the solar spectrum,
  • diameter of the light beam, concentrating 90% of the power, is not more than 20 cm,
  • the power of visible radiation is close to the solar 1367 W / m2 at a distance of at least 0.2 m from the light source,
  • safety for eyes (protection glasses),
  • during the experiment the simulator is stationary and can be easily moved by one person to any distance between the experiment sessions,
  • power supply from a normal 220V network,
  • The presence of a mounting system (tripod), which allows for the smooth adjustment of the light source in height (from 0.5 to 1.5 m), along the slope of the horizon (-60 to 60 degrees).

The sun simulator must be turned on by the user before the experiment is started and manually turned off after the experiment using a conventional switch.
