Osram Introduces New IREDs for Immersive VR/AR Experience

Posted Nov 07, 2019 by OSRAM

While Virtual (VR) and Augmented Reality (AR) usage has become more widespread in the recent years, primarily for gaming, some regular users have often complained of developing feelings of discomfort and dizziness when the virtual and real perceptions do not match. In a bid to help prevent these side effects, Osram, has released its new IRED offerings, the SFH 4030 and SFH 4060. The latest IREDs enable state-of-the-art eye-tracking solutions that provide a targeted point of reference, allowing users to safely immerse in other worlds.

Eye-tracking systems register the user's viewing angle and the movements of his/her eyes. The systems illuminate the eyes with infrared light and register the reflections with a camera sensor. Software then determines the exact position of the eyes and the viewing direction of the user to derive relevant information for the imaging elements of the system. The Firefly SFH 4030 and SFH 4060 feature compact dimensions of only 1.0 mm x 0.325 mm. Thanks to their low height of only 0.55 mm, the side emitting components can be easily installed. A special feature is the black cap, which makes the two IREDs "invisible" when installed.

Customers can choose between the 940 nm version (SFH 4030) or the 850 nm version (SFH 4060), depending on the requirements of their target application. With the SFH 4060, customers benefit from the high sensitivity of the sensors in this wavelength range. On the other hand, the 940 nm version (SFH 4030) avoids the disturbing "red glow" effect, where users see a red light.

According to Bianka Schnabel, Product Manager at Osram Opto Semiconductors, eye-tracking offers a very intuitive way of human-machine interaction for AR and VR applications, including displaying important information about the focused object. With the IREDs’ two wavelength options and black package, Osram has broadened the options for customers, and at the same time, made system integration easier.
