Nexun One

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 Ed. 3, 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.

Patented IR Technology

Avalon’s Nexun One technology for the infrared region coverage is patented!

  • Actual measurements, performance may vary, represents typical results.

  • IEC60904-9 Class A is ±25%, Class A+ is ±12.5%

  • Indicated band deviation values in %


10’000+ LEDs, 3’840 Channels

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.

The standard Nexun One MT packs 3’840 independent, 12-bits fully adjustable channels, providing the utmost control over spectrum and uniformity, beyond anything else on the market.
