We offer traceble measurements of all electric and optic parameters of LEDs in the spectral range 200 to 2500 nm. It is possible to vary- temperature from -10 to 85°C- current from 1 nA to 100 A- voltage from 1 nV to 16 kV (ESD)- optical power from 1 nW to 1 kW- light output from 0,001 to 300.000 lumen- time from 2 ns (permissible pulse handling capability) to 45.000 hours (lifetime).We fullfil all requirements regarding CIE127:2007 and IES TM-21-11 for lifetime. From these data we calculate (e.g.) flicker, efficiency, efficacy, CCT, CRI, LM-70, photobiological safety EN62471 and many more.
