Imagine using your smartphone to analyze your breakfast, lunch and evening meal. Now you can, thanks to the new broadband infrared LED from Osram Opto Semiconductors. The company is using converter technology for infrared emitters for the first time. The result is an LED that emits broadband infrared light in a wavelength range from 650 to 1,050 nanometers (nm), opening up infrared spectrometry for the consumer market. One option would be a compact sensor – like a USB stick – which would be used with an appropriate smartphone app to measure calories, freshness or nutritional content.
