Nexun ULTRA
The Best Uncertainties
IEC60904-9:2020 - 300-1200nm - A+++A++A+++
The lowest uncertainties
The lowest uncertainties thanks to it’s A+++A++A+++ rating, going beyond IEC60409 requirements:
| IEC60904-9 Ed. 3 A+A+A+ | Nexun ULTRA A+++A++A+++ | Class Equivalence | |
| LTI | ± 1% | ± < 0.2% | A+++ |
| Spectral Bands | ± 12.5% | ± < 3% | A+++ |
| Non-Uniformity | ± 1% | ± < 0.5%* | A++ |
A++ Uniformity
We commonly reach sub 0.4% light non-uniformity with a 6 inch cell, exceeding any system on the market.
Best Spectrum
The Nexun Ultra features the best spectrum on the market for a full led system with the lowest spectral deviation, thanks to 37 LEDs types and 32 channels per 15x15cm board area.
Longest pulse for the A+++A++A+++ Class
At 500ms, with an LTI down to 0.1%, combined why the dynamic IV, measure the most capacitive technologies like the latest HJT.
Long Pulse for PERC & HJT
The Nexun Ultra has pulse length of up to 500ms, allowing you to measure even the latest, most capacitive HJT panels in a single flash!
Automatic Uniformity Robot
The automatic uniformity robot allows fast and fully automated measurement of the whole area. The cell size can be adjusted upon needs and the mapping steps and area are fully configurable.
At less than 2 seconds per position, even a 200 points mapping takes less than 10min.
The software integrate a self correction algorithm so that the uniformity can self-adjust in sequence, allowing to reach a uniformity record down to 0.3%.
Want to bring uncertainties even further ? You can configure the robot to match your panel cell position, and measure the uniformity at the same cell position as your panel for maximum accuracy.
TUV Verified
The Nexun Ultra is shipped with TUV Certificate.
Integrated Diagnostic system
System Diagnostic
The Nexun Ultra is able to self assess with its diagnostic tool and check each LED for deflective LED, driver unit or communication issue, ensuring the best measurement at all time.
LED Lighting
Beyond the integrated diagnostic, the LED can also light in steady-state at low intensity and by single wavelength which allows visual check.
HJT Terminator
With its 500ms pulse and the Dynamic IV, no HJT will ever need more than a single flash to be accurately measured.
The Bi-directional Dynamic IV technology and 500ms pulse mean 100 points with each 5ms stabilization, allowing an accurate measure of the most capacitive technologies without complex fitting algorithm or curve shaping.
Active Electronic Load
The 4-quadrant active load allows for the most precise measurement with an accuracy of 0.05% FS.
30A, 300V
0.05% FS
Dark IV
True 4-point kelvin with independent grounds

Advanced Electronic Load
High Hysteresis
The load is optimized for the measurement of high-hysteresis technologies like HJT, ensuring the fastest capacitive discharge of the panel during the measurement.
True 4-point Kelvin Connections
At the difference of most loads on the market, where V- and I- are short-circuited, Avalon’s load has a true, 4-point Kelvin connection with fully isolated I and V channels.
Low Noise, 4’000 Points, 16 bits
The load uses fully independent channels for each of the measured Voltage, Current, and Irradiance. Powered by high speed, 16bit converter with a low-noise optimized front end, a single IV is measured of 4’000 points.
30A, 250V, Multiple Ranges
Measure panels up to 30A and 300V with measurement ranges of 30A, 10A, 4A, 1A, 0.2A and 250V, 180V, 120V, 60V, 15V, 1V
WPVS Channel
A WPVS Reference cell can be directly connected to the load, thanks to its trans-impedance amplifier, removing the needs of an external shunt resistor, further reducing uncertainties.
4 Raytek IR Temperature Sensor
You can connect up to 4 Infrared temperature sensors, ensuring precise monitoring of the temperature.
8 PT100 Channels
The optional PT100 box allows you to connect up to an 8 PT100 temperature probe for a precise measurement of the temperature coefficients.
0.05% Accuracy
The load is guaranteed to an accuracy of 0.05% to the selected measurement range, ensuring the lowest measurement uncertainties.

* Uniformity is guaranteed at 1%, 0.5% is dependent on lab condition, operation of the equipment and knowledge of the user. A stable room temperature and a clean optics is required as well as no external stray light. The uniformity robot is required. Uniformity is rated A++ with a 6 inch cell and 15cm gap to the edge of the illumination area.
