Lumileds launches LUXEON IR ONYX broadband LED for handheld spectroscopy and hyperspectral imaging

At the Mobile World Congress (MWC19) in Barcelona, Spain (25-28 February), Lumileds LLC of San Jose, CA, USA launched the LUXEON IR ONYX LED (available now for sampling) for use in spectroscopy and hyperspectral imaging applications.

The LUXEON IR ONYX LED has a broad, flat continuous broadband infrared (IR) emission spectrum of 650-1100nm without any peaks, enabling ease of calibration.

The broadband infrared emission is enabled by new proprietary phosphor materials developed and manufactured at the Lumileds Phosphor Development Center, allowing it to achieve performance of up to two times what is currently available on the market, it is reckoned. The LED opens up new possibilities for miniaturization of spectroscopy and hyperspectral imaging applications in, for example, hand-held devices for mobile, industrial and medical applications. Due to the low level of heat generated comparison with traditional IR light sources like incandescent halogen technology, the LUXEON IR ONYX is suited to applications that are sensitive to heat, such as those found in the fruit and vegetable industry.

An industry-standard 2720 package and footprint allows easy integration in existing designs. “The small source size and package dimensions allow the LEDs to be closely packed and placed close to the inspection subject without the risk of overheating,” says Wouter Schrama, senior product manager for the LUXEON IR portfolio.

“The small size and high infrared power output takes us a step closer to the challenge of taking food quality measurements in the field, and ideally from our smart phone,” says Noman Rangwala, director of business development. “We continue to work with sensor and eco-system partners to make hyperspectral imaging a reality in handheld devices.”
