LSG-1800/LSG-1700/LSG-1600 Goniophotometer is high precision automatic goniophotometric instrument for luminous intensity distribution measurements with facility for turning the light source. The LSG-1800 is an update version for LSG-1800, the LSG-1800 use a high accuracy Motor and precision angle coder which keeps high test accuracy. It is for industrial laboratory measurements the photometric data of luminaries such as LED luminaries, HID lamps, fluorescent lamps and so on.



  • Meets the requirements of CIE, IEC, IES LM-79 & GB standards
  • Reaching many measurement ways such as B-Beta & C-Gamma (LSG-1800) and C-Gamma (LSG-1700/LSG-1600)
  • The tested luminaries rotates around an angle of (γ)±180°(or 0-360°) and the tested luminaries rotates around itself with an angle of (C)±180°(or 0-360°)
  • Luminosity Testing Range: Illuminance 0.001lx~10,000lx; Light Intensity 1.0cd~107cd(detector)
  • The accuracy of angle: 0.01° (LSG-1800) and 0.1° (LSG-1700 and LSG-1600)
  • Accuracy of photometry: Class 1
  • Testing Accuracy: 3%(Under Standard lamp); Stray Light: less than 0.2%
  • English version software can run in WinXP, Win7 or Win 8
