ISOSun Vis
A compact, high-precision solar simulator with tunable LED channels, Class A spectral uniformity, and excellent temporal stability
Ultra Compact Solar Simulator
The ISOSun Vis is a compact solar simulator designed for precise light condition simulation in the 390–700 nm range. Equipped with six independently tunable LED channels, it allows accurate reproduction of both indoor and outdoor spectra, including an AM1.5G setting. With Class A ratings for spectral uniformity and temporal stability, the ISOSun Vis ensures reliable and consistent measurements, making it ideal for small to medium-sized solar cell testing and controlled illumination experiments. Its lightweight design and included software make it easy to use in laboratories, offices, or research environments.
Key Features
Adjustable spectrum (390–700 nm) with six tunable LED channels (UV, blue, green, amber, red, white)
Class A spectral uniformity and Class A short- and long-term temporal stability
Overall intensity and relative spectral tuning, including AM1.5G setting (0–47,500 lux)
Compact design (37 × 22 × 22 cm, 5.8 kg) for easy lab or office placement
Free software for spectrum matching to reference standards
Suitable for small to medium-sized solar cells and controlled illumination research
Total intensity: 0–131,400 lux (UV: 0–14,490, Blue: 0–52,900, Green: 0–28,200, Amber: 0–9,580, Red: 0–13,400, White: 0–54,500)
Spatial uniformity: Class A (30 mm), Class B (40 mm), Class C (55 mm)
Spectral Irradiance
Easy tuning of 6 individual LED outputs (UV, blue, green, amber, red and white light), allows for easy tuning of simulated indoor light conditions. A simulator program, provided with the lamp, furthermore, gives you the possibility to easily find the settings of the lamp to fit the spectral output to a reference spectrum. Besides relative tuning of the individual colours the lamp allows for variating the overall light intensity as a single entity.
Spatial Uniformity
The measure that is used to describe the evenness of a light source is called the spatial uniformity. Below is shown the spatial uniformity of the ISOSun Vis, showing areas to be rated class A, B and C with respect to uniformity. The high uniformity, especially in the class A area around the centre of the lamp, makes it ideal for testing of small to medium sized solar cells.
Temporal Instability
The ISOSun Vis shows excellent stability over time being class A in both short-term and long-term temporal instability. The high stability over time allows for consistent measurements of your devices.
