The New Standard of PV Metrology

IEC60904-9 Ed. 2: A+A+A+
IEC60904-9 Ed. 3: A+A+A+


Meet the Standards of Today and Tomorrow!

Unrivaled Spectrum

From the Standard

The Nexun One ensures that you meet the highest industry standards. Its spectrum reaches A++ for both IEC60904-9 Ed 2. and Ed3., with a SPD lower than 15% and SPC higher than 98% over the 300-1200nm range. Its spectral deviation is lower than Xenon and traditional LED solar simulators.



Leds provides the longest lifetime. Each LED are monitored in temperature, voltage and current to ensure stable operation and automatic fault detection for worry-less operation. Boards are easily replaceable by the end-user, and spare parts are provided, removing the need to wait for a service engineer.
