Freestanding goniophotometer LGS 650

Goniophotometer for medium and large light sources Angle-dependent determination of photometric quantities The LGS 650 was specially developed for the determination of angle-dependent spatial radiation properties of medium-sized to large SSL sources and LED modules, and is a space-saving and attractively priced alternative to the larger LGS 1000. The sample is measured in a horizontal burning position and moved over an angle range of ± 160° in the direction of radiation of the sample around the gamma axis. The high angle resolution of 0.01° guarantees highly accurate and reproducible readings. The LGS 650 permits the mounting of samples with a diameter of 1300 mm and a maximum weight of 10 kg. It complies with all relevant CIE, DIN and IES standards. Combined with an Instrument Systems spectroradiometer, e.g. the CAS 140D, radiometric, colorimetric and photometric quantities can be determined with the greatest precision as a function of angle. For particularly time-critical measurements, Instrument Systems offers the appropriate photometers. LGS 650 – Highlights: - Type C goniophotometer for samples with a diameter up to a 1300 mm and a weight of 10 kg - Precise determination of luminous intensity distribution and luminous flux - Angle-dependent analysis of spectral and colorimetric quantities - Data export in IES and EULUMDAT format - Easy and intuitive control of the measurement process, as well as power supply and electric measurement of the sample - Configurable switch-on and stabilization routines for the sample in repetitive measurement tasks
