Osram introduces the new Oslon P1616 SFH 4737 wide band infrared LED

     Osram has introduced the new Oslon P1616 SFH 4737 wide band infrared LED. This product is not only the world's smallest wide-band infrared LED with its ultra-compact package, but also has excellent output power and positive radiation intensity, and effectively reduces energy consumption through the new phosphorus technology. The Oslon P1616 SFH 4737 Wide-band infrared LED enables mobile spectral solutions to become a reality faster and is ideal for manufacturing smartphones.

     For many years, OSram Opto Semiconductors has been a leader in the research of compact, high-intensity, wide-band infrared emitters for spectral applications. In addition to the wide wavelength range, features such as high energy efficiency and small size of integrated components are also critical for system manufacturers. Osram's Oslon P1616 SFH 4737 combines these advantages to provide customers with an even better choice.

     Are the shirts on the shelf made of 100% cotton? Supermarket apples may look delicious, but have they gone bad and lost nutrients? A closer look at its molecular structure can answer these questions. For light sources in the near infrared spectrum, the most important point is to cover as wide a range of emitted light wavelengths as possible.

     The wider the coverage, the more objects can be analyzed. To determine the composition or moisture content, the target object needs to be illuminated with a wide band of infrared light (usually 650 1050 nanometers), at which time part of the light source will be reflected and another part will be absorbed. The reflection-absorption ratio varies from object to object, so a molecular fingerprint of each object can be obtained. The reflected light is collected by a special detector, which is then processed by software and compared with information stored in the cloud to produce the final measurement.

     The OSRAM P1616 SFH 4737 offers an ultra-compact package of 1.6mm x 1.6mm x 0.9mm, which also makes it the smallest near-infrared LED (NIRED) for spectral applications on the global market - half the size of the smallest OSram products available today. The NIRED's compact design makes it ideal for manufacturing smartphones, but it also guarantees an excellent output of 74mW at 350mA - roughly three times the peak of its predecessor. In addition, the positive radiation intensity of this new product can reach 18mW/sr, which is double that of the previous Osram NIRED product.

     Oslon P1616 SFH 4737's superior performance over the full wavelength range gives it another unique advantage in the field of spectroscopy. The sensitivity of common silicon-based detectors decreases with increasing wavelengths (especially those above 950 nm), and in the past increased currents were needed to compensate for this. With the support of a new phosphor, this new product can emit more light at higher wavelengths - reducing the overall energy consumption of the system.

     Carola Diez, Product Manager, OSram Opto Semiconductor Sensing, explains: "The Oslon P1616 SFH4737 demonstrates once again our extensive experience and excellence in the infrared field. In mobile spectrum applications, our NIRED can help identify not only food freshness, but also counterfeit medicines and banknotes. In agriculture, it can also be a key tool to help identify optimal harvest times."
