Osram’s Broadband Infrared LED Named CES 2018 Innovation Awards Honoree
SFH 4735 Emitter Allows Consumers to Analyze Food, Medicine and More on Mobile Devices
27.10.2017 | Awards
Osram Opto Semiconductors is thrilled to announce its SFH 4735 emitter was selected as an honoree for the prestigious CES 2018 Innovation Awards in the Embedded Technologies category. Each year, the Consumer Technology Association (CTA), organizer of the world-renown CES show, honors an exclusive group of innovations based on outstanding design and engineering in consumer technology products. CTA announced the European honorees on Thursday, October 26, 2017 at CES Unveiled Amsterdam. Osram will showcase its latest innovations in Booth 3115 in the North Hall at the CES show in Las Vegas, Nevada, January 8-12, 2018.
Near Infrared Spectroscopy Expands Biomonitoring
The SFH 4735 LED emits broadband infrared light in wavelengths ranging from 650 to 1,050 nanometers (nm). It is ideal for near-infrared spectroscopy, which can be used to assess food, medicine and even measure body fat. The SFH 4735 created a whole new field of compact, robust and low-cost sensing technology that did not exist before, making it possible to integrate spectrometers directly into mobile devices like smartphones and tablets.
Before SFH 4735, infrared spectrometers often used light bulbs, which created bulky machines mainly found in laboratories. Now, with the LED-based SFH 4735, consumers are able to measure nutrients, calorie content and freshness in foods with the same handheld devices that also measure heart rates and pulse oximetry. Spectroscopy is another piece in the puzzle of an increasingly networked world. It supports the trend of using technology to optimize our own well-being.
First converter for infrared emitters
The basis of the SFH 4735 is a blue 1 mm2 chip in UX:3 technology. Its light is converted into infrared radiation with the aid of a phosphor converter developed specifically for this application. A residual blue component in the light helps users target the area they want to investigate. It features a wide viewing angle of 120 degrees and also offers improved corrosion robustness. The chip is mounted in the proven and compact Oslon Black Flat package, which has excellent thermal resistance.
Measuring freshness with a smartphone
Infrared spectroscopy uses the absorption behavior to determine molecular compounds. Every molecule absorbs light at several, specific wavelengths. This absorption spectrum is unique and acts like a fingerprint for a particular molecule. By analyzing the absorption spectrum of an unknown material and matching this measurement with a database of known molecules, it is possible to determine the presence and quantity of certain ingredients.
Infrared spectroscopy is used to identify certain compounds like fat, sugar, water or proteins in food. This leads to information about calorie content, freshness and quality of food that helps consumers better monitor their health and reach their fitness goals.
