On March 3, 2016, Dalian United Holdings, a leading semiconductor component distributor dedicated to the Asia-Pacific market, announced that its product has launched an iris recognition solution based on OSRAM (Osram Optoelectronics) SFH 4786S infrared LED (IRED). Program. With a thickness of 1.6 mm, this new IRED makes it easy to achieve a slimmer iris recognition system. Its own light direction is slightly inclined, so there is no need to add any mechanical aids to adjust the light direction. The solution has already cooperated with companies such as Zhongke Hongba, Shima Dahua and DELTA.

Identifying different iris images between people is one of the most reliable biometric methods. Recently, this technology has been applied to smartphones and tablets to prevent unauthorized access. OSRAM (Osram Opto) introduced the first IRED that integrates compact, highly reliable iris recognition into mobile devices in 2014, while the latest SFH 4786S offers increased compactness and performance for higher performance. Design requirements for a slimmer transmitter.

For cameras mounted at a distance, the slightly tilted emission characteristics are very beneficial to their field of view, and the overall system performance is significantly better than systems equipped with vertical up-emission transmitters. Therefore, the iris recognition system so far has been mechanically used to slightly tilt the IRED. The launch direction of the SFH 4786S, which is represented by the company, is tilted by 8°. Bianka Schnabel, marketing manager at OSRAM Opto Semiconductors' German headquarters, said: "With the SFH 4786S, these additional materials and installation costs can be saved. And for the customer, this greatly reduces the design complexity of the iris scanner." The application also benefits from the slightly widened emission angle (+/-13°) of the IRED, which allows the mobile device's built-in iris scanner to illuminate a larger area at normal working distances, and the illuminated area is more evenly illuminated. At a current of 1 A, the typical radiant intensity of the SFH 4786S is 1.750 mW/sr.
