Instrument Systems Light Measurement

Analyze the angle dependent spatial radiations properties of large SSL lamps and LED modules with the new LGS 1000 goniophotometer or goniospectroradiometer. The LGS 100 is capable of measuring LED modules up to a length of 1900 mm and weight 50 kg. The LGS 1000 has a much simpler setup for measuring path due to its Type C design and horizontal optical axis. This makes it far superior than complex mirror goniophotometers and it still maintains impressive dimensions of 1850 x 1492 x 1798mm.

All spectral quantities like color temperature, color coordinates, and even color rending index determined as a function of angle when using the LGS 1000 with a spectroradiometer from Instrument Systems. By using an Optronik DSP Photometer, C-plane measurements can also be carried out quickly.

The LGS 1000 features a sample plate for fixing the test specimen and the LGS controller. It also comes with accessible steps for easier mounting of test specimens. The LGS Controller comes integrated in a large 19” rack and displays the angle while driving the servo motor. If necessary, it can also show the measured values in candela or lux.
