Osram Introduces Near-infrared LED for Spectroscopy Applications, Helping to Check Food Quality

Is the blouse on the shelf truly composed of 100% cotton? Is the apple in the supermarket spoilt and vitamin deficient, or does it merely appear to be delicious? The responses to these enquiries can be obtained by conducting a more thorough examination of the molecular structure. This is facilitated by near-infrared spectroscopy. For numerous years, Osram Opto Semiconductors has been engaged in the development of broadband infrared LEDs that are both compact and exceptionally potent, with a focus on spectroscopy. The compact dimensions and energy efficiency of the integrated components are indispensable to system manufacturers, in addition to the broad wavelength range. Osram's Oslon P1616 SFH 4737 integrates these attributes and provides consumers with additional advantages. Mobile spectroscopy solutions will soon become a reality as a result of this product.
The most critical aspect of infrared light sources for near-infrared spectroscopy is to encompass a wide spectrum of wavelengths in the emitted light. The greater the range, the greater the number of objects that can be analysed. The target object is suffused with infrared light of a broad wavelength range (typically 650 to 1050 nanometres) to ascertain the water content or constituents. Some of this light is absorbed, while others are reflected. The molecular fingerprint of each item is distinctive due to the fact that this ratio varies from object to object. A specialised detector is employed to capture the reflected light. This data is subsequently processed by software, which compares it to documented information recorded in the cloud and subsequently generates the measurement results.


Osram's Oslon P1616 SFH 4737, which the company asserts is the world's smallest near-infrared LED (NIRED) for spectroscopy applications in the market, has dimensions of 1.6mm x 1.6mm x 0.9mm. It is suitable for use in portable devices. It also produces an output of 74mW at 350mA, which is approximately three times the maximal values of previous products. In addition, the new product doubles the values of former Osram NIREDs by providing radiant intensity in the forward direction at 18mW/sr.
The component addresses the issue of silicon-based detectors, which frequently experience a decrease in sensitivity as the wavelength increases, particularly above 950 nanometres, by integrating new phosphor technology to emanate more light at higher wavelengths.


"Our NIREDs are employed in mobile spectroscopy applications to identify counterfeit medicines and banknotes, in addition to determining the freshness of food." "In agriculture, they are a critical tool for determining the optimal harvesting time," stated Carola Diez, Product Manager in the Sensing Division at Osram Opto Semiconductors.
