ams OSRAM launches FIREFLY SFH 4030B and SFH 4060B IREDs
ams OSRAM GmbH of Premstätten, Austria and Munich, Germany has launched the new-generation FIREFLY SFH 4030B and SFH 4060B infrared light-emitting diodes (IREDs), which are claimed to set new standards for infrared LEDs in augmented reality (AR) and virtual reality (VR) applications such as eye tracking in smart glasses and AR/VR headsets.
VR is advancing toward unprecedented levels of immersion, seamlessness, energy efficiency and connectivity. This is made possible by innovations that, while compact, have the power to fundamentally redefine the user experience, operating at the core of next-generation devices, says ams OSRAM. The new-generation FIREFLY IREDs SFH 4030B and SFH 4060B IREDs are said to meet the demands of next-generation AR and VR headsets. Leveraging advanced IR:6 thin-film chip technology, they deliver up to 50% brighter infrared illumination and 33% higher efficiency, resulting in longer battery life and optimized system performance.
Notably, the new generation of FIREFLY SFH 4030B and SFH 4060B are the first in their class to feature a fully black package, setting a new benchmark in terms of discreet integration, it is claimed, and offering maximum design flexibility for nearly invisible placement in AR/VR headsets and smart glasses. Specifically designed for eye tracking, an additional new 930nm wavelength has been introduced. It offers an extra option to operate the system within the optimal range of maximum camera sensitivity, while simultaneously minimizing the red-glow effect.
“With the new generation of FIREFLY IREDs, we provide AR/VR headsets and smart glasses with a compact and efficient solution for biometric applications,” says product manager Markus Heller. “The combination of high performance, small size and flexible integration with the new all-black package supports the development of modern, user-friendly devices.”
The launch of the new FIREFLY generation is in line with key trends in VR and AR. As headsets become lighter and wireless, there is growing demand for compact, energy-efficient components. Eye tracking and other biometric features are becoming the standard, enabling intuitive interfaces and advanced analytics. Cloud-based VR is increasing, requiring reliable hardware for real-time rendering and AI features. The new generation of FIREFLY IREDs meets the demands of modern AR and VR applications while emphasizing sustainability, offering long-term availability and robust qualification for extended lifetimes across industries such as healthcare, education, and entertainment.
The FIREFLY SFH 4030B and SFH 4060B are suitable for smart glasses with advanced eye tracking and iris scanning, as well as optical sensing in mobile, wearable, and industrial devices.
