Goniophotometer targets mid- to large-sized SSL sources
A comprehensive software package facilitates easy evaluation and reporting of the measured data, which can also be exported in standard file formats like IES and EULUMDAT. The LGS 650 goniophotometer was developed for the analysis of angle-dependent spatial radiation properties and offers a cost effective alternative to the LGS 1000. 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.
Spectroradiometers offer the distinct advantage that all radiometric, colorimetric or photometric characteristics can be determined with maximum precision. Instrument Systems also supplies very fast photometers to perform integral measurements. Combined with the LGS 650, the photometers allow ‘on-the-fly’ measurements, meaning the measuring system records the light distribution while the goniometer is moving. The LGS 650 is operated via the goniometer module of the SpecWin Pro software. The software routinely performs measurement sequences to record the spatial radiation pattern of the test specimen.
