Pulsed xenon: less Star Trek, more semiconductor inspection
Why pulsed xenon has powered semiconductor inspection for decades, and why OEMs are increasingly turning to LED illumination instead

Follow a silicon wafer through months of lasers, plasma, microscopic layering and LED inspection to see how one of humanity’s most ridiculous manufacturing feats becomes a working semiconductor.
Meet Duncan, our Global BDM for Industrial Applications, supporting OEM partners worldwide with LED Illumination for imaging and inspection
Visible light has had a very good run, but longer wavelengths are helping imaging systems reveal what the human eye politely ignores…
How LEDs support stable, repeatable semiconductor inspection and metrology
Meet CoolLED at SPIE BiOS and Photonics West 2026 to explore custom OEM LED Illumination built for a huge range of applications
Join our webinar, where four leading technology providers will come together to showcase how our systems fit seamlessly to power next-generation imaging and inspection platforms
Visit us at Semicon Taiwan 2025 – K2169 – and discover our Amora LED Illumination platform for semiconductor inspection
Switch from outdated lamps to fast‑switching LEDs and you’ve got a toolbox full of spectral, timing and polarisation tricks that mercury could only dream of
Need something a little different?
For manufacturers who wish to gain a competitive advantage through bright, stable and controllable illumination, CoolLED’s world-renowned LED technology is available in customised configurations.

Did you know that LED illumination systems help laboratories reduce their carbon footprint, protecting laboratory staff along the way?
Toxic mercury-based microscope illuminators are bad news for the environment, draw a lot of power and have a short lifetime.
LED illumination systems are cleaner, have a long lifetime and use less power. Our pE-300 Series is also ACT label certified and is a natural choice for labs who want to play their part in helping the environment.
At CoolLED we are committed to giving our customers outstanding service right from the start and throughout the lifetime of the product. Please get in touch if you have any questions or would like a quote. You can also browse our site for technical resources and general support.
