the Observatory's material resources

Lighting diagnostic and light pressure metrology equipment

  • Konica-Minolta CL-70F spectrophotometer (measures illuminance, irradiance, colour temperature, wavelength and colour rendering index);
  • Leica laser rangefinder for measuring the heights of streetlights;
  • Fusion Optix Pro luminance meter (this tool can be used to assess differences in luminance and thus identify excessive contrasts for the human eye);
  • Field GIS for public lighting diagnostics, with customised input fields, Open Street Map (OSM) and satellite backgrounds, and Galileo positioning system on the smartphone (accuracy greater than 4m);
  • Analysis tools to determine biological impact indices based on spectral data from light sources;
  • Minolta luxmeter;
  • Stand-alone SQM photometers (continuous measurement and recording of night sky brightness, GPS position, air temperature and humidity);
  • Cup anemometer (resolution 0.1 m/s);
  • Network of TESS-W photometers (in conjunction with the Stars4All project team and, on Reunion Island, the Société d'études ornithologiques de La Réunion).
