System provides accurate and reproducible LED measurements


To more easily meet new reporting specifications, thermal/optical/electrical LED measurement system (TOCS) enables measurement of optical properties as a function of temperature and operating current using a single instrument. The instrument complies with IESNA LM-79 and LM-80 standards, delivering accurate and reproducible LED measurements. Available in a range of integrating sphere sizes from 20 to 76 in, the system is designed for both 2pi and 4pi measurement geometries. A lamp measurement integrating sphere, high resolution CCD array spectrometer, thermal plate with temperature controller, auxiliary lamp, calibration source, power supply and software comprise the basic system.
