Broadband infrared LED emitter serves near-infrared spectroscopy

November 7, 2016  Stephen Law

OSRAM SFH 4735 LED emits broadband infrared light in a wavelength range from 650 to 1,050 nanometers (nm). Device is based on a blue chip and a special phosphor converter. Product’s main application is near-infrared spectroscopy for analyzing food quality. Infrared spectroscopy uses the characteristic absorption behavior of certain molecular compounds. If a defined spectrum is directed at a sample, it is possible to determine the presence and quantity of certain ingredients from the wavelength distribution of the reflected light. https://www.osram.com/os
