LGS 350 Goniophotometer
Perfect for mid-sized SSL light sources and LED modules
The LGS 350 Goniophotometer / Goniospectroradiometer was developed for the analysis of angle-dependent spatial radiation properties from small to medium-sized SSL luminaires and LED modules. The test specimen is operated in a horizontal burning position and measurements can be taken at an angular range of ±160° in the gamma / theta axis.
Combined with a spectroradiometer from Instrument Systems, all spectral quantities such as color coordinates, color temperature and even color rendering index are determined as a function of angle. The Optronik DSP Photometer can also be used to carry out C-plane measurements very quickly “on the fly”.
The complete system
The LGS 350 comprises the goniometer with a sample plate for fixing the test specimen and the LGS Controller that drives the stepper motor and the angle display. If a photometer is used, the LGS Controller also displays the measured values in candela or lux.
The following versions of the LGS 350 are supplied:
