The SFH 4736 from OSRAM is a near-infrared LED (NIRED) to help farmers and vineyard owners to gage the right time for the harvest. Simply scanning fruit or cereal crops with the NIRED installed in a smartphone or tablet produces reliable information about the sugar, water and fat content.
The SFH 4736 is based on a highly efficient, blue-emitting chip in UX:3 technology. A phosphor converter specially developed for this application converts the blue into infrared light with a wavelength range of 650 nm to 1050 nm. It is 2.3 mm high and has a footprint of 3.75 mm x 3.75 mm. When compared to SFH 4735, without a lens, the SFH 4736 also achieves more than twice the output in a solid angle of 80 degrees. It, therefore, marks another step toward even more efficient broadband NIREDs for spectroscopy applications.
