The LGS 350 Goniophotometer/Goniospectroradiometer was created to analyze angle-dependent spatial radiation properties. This particular model is best used with small to medium sized SSL luminaries and LED modules. Test specimens operate from a horizontal burning position. Measurements can be taken at an angular range of plus or minus 160 degrees in the gamma theta axis.
When used in conjunction with Instrument Systems spectroradiometer, all spectral quantities such as color temperature, color coordinates and color rendering index are determined as a function of angle. Carry out C-plane measurements very quickly when using the LGS 350 with the Optronik DSP Photometer.
The Complete System: The LGS 350 Goniophotometer comes with a sample plate for securing the test specimen. It also has an LGS Controller that controls the stepper motor and angle display. When a photometer is used with the LGS 350 the LGS controller displays measured values in candela or lux.
