Flexible Illumination with Unbeaten Spectral Match

Sunglasses. Auto tint. Photochromic, switchable smart glass. You’re developing and manufacturing the next generation of glass technology that’s far more than just a window. There’s incredible structure and uniqueness sheathed between the panes of your innovation.

Your materials exhibit some of the most advanced known glass principles and technology, such as dynamic thermochromic glazing, integrated sun protection, and liquid-crystal polymers. You need glass that resists breakage while maintaining optical clarity, touch sensitivity and damage resistance. You’re on the leading edge, and your materials are finely tuned to give precise results.

You need a reproducible light to output the exact spectrum required, no questions asked. But you also need a light you can adjust to investigate the unexpected spectral properties you’ll encounter en route.

G2V’s solar simulators give you the best of both worlds: the lowest spectral deviation and best spectral match of any commercial solar simulator, along with the ability to tune and customize any LED on the system.

Multi-tool lights that don’t compromise.

The Most Advanced Technology For Your Cutting Edge Research

You’re building something great. Our solar replication technologies mean you don’t have to worry about accurate light.


Pico™ Solar Simulator for Glass Testing

Your new glass formulas start with small samples, but even at small scales you need reliable testing with high-quality sunlight. The Pico small-area solar simulator provides industry-leading spectral coverage and the lowest spectral deviation, all with a form factor and illumination area perfect for initial sample validation

Exceptional sunlight to quickly validate your samples and accelerate your glass tech’s development. 


Sunbrick™ Solar Simulator for Glass Testing

You’re moving from small samples to larger panels or windows, and need to ensure your glass's innovative behaviours haven't been compromised in up-scaling. The Sunbrick large-area solar simulator has a tileable design that can accommodate arbitrarily large areas so you can fully illuminate large samples.

How the Sunbrick Charged SWITCH Materials Automotive Glass

Problem: SWITCH Materials had developed switchable, photochromic glass technology that was ready to commercialize in the automotive sector. They’d demonstrated its functionality at small scales but needed to execute a litany of certification tests on larger, sunroof-sized substrates.
Innovation: G2V provided them with a custom visible spectrum (400 nm – 700 nm ) array of 128 Sunbricks to provide illumination in a 2 m x 4 m area that minimized cost while still producing the key spectral signatures they were interested in.

Outcome: SWITCH Materials was able to execute full-module glass testing and make steady progress on meeting the many rigorous requirements needed for certification and approval in the automotive sector.

The Sunbrick Class AAA Large-Area LED Solar Simulator

Better testing illuminates the future with higher-quality predictions.

Whether you’re developing sunglasses or windshields, smartphones or EV sunroofs, your devices need to be tested with a large, uniform sunlight source. G2V’s Sunbrick Class AAA LED solar simulator is built to accommodate your testing in early samples, as well as when you scale up to full prototypes. Its tileable nature means it can grow with your product development.

Some of its features include:

  • Large base 20 cm x 20 cm area to fully illuminate your samples
  • Tileable into arbitrary array sizes to scale with your sample sizes
  • Exceptional Class A spectral match to accurately test spectral sensitivity
  • Individual LED control of up to 36 channels to probe any spectral regions of interest

It gets the job done, so you can get the results you need.


How Solar Simulators are Qualified for Demanding Tests

You have high standards for the light you need. You know your glass well, but you might not be sure about what light source is the right fit for you.


Our comprehensive solar simulation article can help you better understand what considerations are taken into account in the construction and classification of solar simulators, so you can make informed requests for information as you’re seeking a test solution.


Some of the topics covered include:

  • How light is standardized
  • Nomenclature for different spectra
  • The pros and cons of different solar simulator types

G2V's FAQs

Yes! We’ve done live-streamed demonstration tests on customer samples in the past, and if you have particular spectral concerns that might be addressed by a demonstration, we’d be happy to try and arrange that.

Welding torches typically have very sharp spectral emissions which don’t necessarily align with the peaks produced by the LEDs in our solar simulator. However, we recommend getting in contact and we can share the best spectral match we’d be able to produce for this spectrum, and you can assess if it meets your needs.

The Sunbrick’s uniform area is square-shaped, and it decreases in size as you increase the working distance and move farther from the working plane. As long as you’re within the central region, the intensity drop-off is minimal and is likely still within your requirements, allowing you some flexibility to illuminate substrates that have depth as well as length and width.

For any spectrum outside of the standard air masses like AM1.5G and AM0, we recommend getting in touch with us so we can provide advanced information on the expected spectral match we can produce, so you can make an informed decision. If you decide to purchase, we will include calibration against the spectral standard(s) you provide.
