GONIOPHOTOMETER LMT GO-FI

Goniophotometer for measurement of luminous flux

Total or zonal luminous flux of lighting devices is measured in their dedicated burning position with respect to gravity.

  • Illuminance distribution is recorded either in C-planes or on conical surfaces
  • Goniometer with rotating photometer
  • Maximum device diameter 3000mm
  • Max. test object load 50 kg

Supported standards
