Instrument Systems Goniophotometers
If you need assistance measuring angle dependent spectral measurements, Instrument Systems has developed a comprehensive line of goniophotometers to meet your needs. Instrument Systems Goniophotometers are used to analyze angle dependent spatial radiation properties of SSL lamps and LED modules. Instrument Systems has two varieties of goniophotometers, one used for Large SSL lamps and LED modules as well as one designed for use in small to medium SSL Luminaries and LED modules. These instruments are capable of exporting data in an easily readable EULUMDAT format and provide exceptionally accurate measurement of luminous intensity distribution and luminous flux. The LGS 1000 model has an optional addition of a luminous flux integrator. Instrument Systems also offers a Type C Design for that particular goniophotometer model which is designed with a horizontal optical axis. This makes setting up a measuring path much simpler and allows measurements for specimens up to 1900mm in diameter.
Model Overview
The LGS 650 goniophotometer was developed for the analysis of angle-dependent spatial radiation properties from mid- to large-sized SSL sources 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 axis. The angular resolution of 0.01 ° enables very fine measuring grids recorded with a high level of accuracy and reproducibility. The LGS 650 is compliant with all relevant specifications in conformity with CIE, DIN and IES standards. The probes may have a diameter up to max. 1300 mm and a maximum weight of 10 kg.
