for mid- to large-sized SSL light sources and LED modules Perfect The optical probe of the spectro radiometer or the photometer head for taking measurements is placed outside the photometric distance and attached to a stray light tube adjusted to the measuring distance and the sample size. The measuring distance should be 10 to 15 times the diameter of the light source being tested. The LGS 650 Goniometer rotates the test specimen in the gamma and C axes. The horizontal alignment of the CIE 121-1996 coordinate system facilitates a particularly compact test setup. Both axes can be operated simultaneously...

The full spectrum of measuring options A universal sample holder for mid- to large-sized LED modules and lamps, and a lamp holder for standard fittings of the type E10, E27, E40, etc. are supplied. Sample holders for TEC test adapters of the LED-850 and LED-870 series are available. The test adapters facilitate the analysis of thermal properties of single LEDs, LED arrays and modules using minimum resources. The Peltier elements integrated in the test adapters permit adjustment over a wide temperature range from +5 °C to +85 °C. 02 \\ The full spectrum of measuring options Depending on the specific...
