Checking food with a smartphone thanks to a broadband infrared LED from Osram

Consumers will soon be able to use their smartphones to check how fresh supermarket food is, measure the calories in canteen meals and verify whether the tablet in their hand really is a painkiller. All thanks to the development of broadband infrared LEDs (IREDs) that emit in a wide wavelength range. When Osram Opto Semiconductors presented the Oslon Black Flat SFH 4735 at the end of 2016 it opened up the consumer sector to this technology. To date, Osram is the only one to offer such IREDs. With the tiny SFH 4776 spectroscopy applications can be integrated into smartphones.
