Reliable solar degradation testing through the entire life cycle

You’re developing novel materials and innovating products that improve our quality of life. Your work might be in packaging, plastics, electronics, polymers, coatings, construction or aerospace, you need to make sure the material will last.

You don’t have the luxury of spending 25 years to wait and see. 

You need accelerated weathering and photodegradation tests that accurately represent the environmental degradation your material will experience in the real world. You also need to explore how chemical degradation is very specific to the environmental conditions that will affect the outcomes of your testing. The commonality that binds these three types of testing is accurate and consistent light.

Your ideas are shaping the world. Your testing equipment shouldn’t limit it.

Our class AAA LED solar simulators allow you to go for the next great idea without worrying about its testing limits. Built for >10,000+ hours compared to 1,000 hours for typical xenon and metal halide, designed to be flexible by swapping between AM0 and AM1.5 (and potentially more upon request) with a click of a button, and created to be low maintenance requiring no calibration and minimal warm-up times. 

Whether you’re working on lab tests or final large-scale product validation, our lights will guide your testing with real-world light simulation.

Terrestrial to extraterrestrial testing with one device

Materials testing on Earth is mandatory for most solutions. What happens when the product you are testing must leave our planet? Do you buy another device just for that one product? You could, or you could look for a solution that can switch between the two if the need ever arises. 

All of G2V’s solar simulators come with the ability to simulate AM0, AM1.5, and with special requests up to AM40. Sometimes your research still requires a highly customized solution. We have built a 4-Sun LED solar simulator for one such time. The researchers using this custom solution required high-intensity accelerated testing to go from .1 to 4 suns.

You have specific needs. We can create the solution.

How the Pico Enabled Glove Box Light Testing

Problem: A researcher needed to evaluate light-induced surface modifications of inorganic materials deposited on a substrate. These materials were sensitive to oxidation, they needed to be manipulated and tested in an inert atmosphere alongside other tools and equipment.

Innovation: G2V provided them with the Pico class AAA LED solar simulator. This small-area solution features a compact design suitable for placement and can work inside a glove box or fume hood environment. 

Outcome: The researcher was able to add solar load testing to their complement of material assessment tools. The Pico’s network control functions and Python integration allowed them to configure the light output remotely for specific periods of irradiation, reducing the need to continuously manipulate their samples inside the controlled environment chamber. Thus, they could characterize their delicate materials without significantly impacting their existing lab and testing setup.

G2V's FAQs

No, we don’t need to know about your proprietary tech, and are willing to sign an NDA if needed. We’ll ask you a few questions about the dimensions (both area and volume) you’re trying to illuminate, as well as what your most important specifications are, but we’ll respect your confidentiality while still delivering an excellent solar simulator.
The LED junction temperatures reach maximum temperatures in the realm of 70 C – 100 C (and that’s only at max current). This thermal energy is in a small area and it’s dissipated through our sophisticated cooling systems. The net result is that the actual LED card operates closer to 30 C – 40 C, so the excess thermal radiation from the heat of the light source is quite minimal, and not something you have to worry about for most applications. Unlike xenon or metal halide lamps, LEDs are very efficient at producing the desired radiation at the wavelengths of interest, without burdening you with the added challenges of having to manage excess heat in your samples. If you’ve traditionally used xenon or metal halide lamps in your testing, LEDs will be a paradigm shift.

No – our solar simulators are designed for indoor use only. However, their tunability means they can produce any outdoor spectrum under laboratory conditions.

While a single Sunbrick’s total illumination covers 25 cm x 25 cm, we guarantee a Class A spatially uniform area in the central 20 cm x 20 cm square. For arrays, the Class A area will be dependent on the array size, and scales along with the array. If you require a larger class A area, please get in contact, and we can discuss some options for meeting your needs.

Not currently. UVC (UV-C or Ultraviolet-C) radiation refers to wavelengths between 100 nm and 285 nm. While producing these wavelengths using LED technology is possible, it is currently inefficient and under ongoing research, making it cost-prohibitive to currently do this type of testing with LEDs. However, G2V continually monitors LED material developments and is very interested in designing a solar simulator with this capability once it becomes more commercially viable, so stay in touch if this is of interest to you in the future.

No. Ozone production requires UV radiation less than 240 nm in wavelength, and our solar simulators do not produce radiation in this range.
