Infrared LED
PerkinElmer Optoelectronics
Light Emitting Diodes (LEDs) are solid-state P-N junction devices that emit light when forward biased. An IRED is an Infrared Emitting Diode, a term specifically applied to PerkinElmer IR Emitters. Unlike incandescent lamps, which emit light over a very broad range of wavelengths, LEDs emit light over such a narrow bandwidth that they appear to be emitting a single “color”. Their small size, long operating lifetimes, low power consumption, compatibility with solid-state drive circuitry, and relatively low cost make LEDs the preferred light source in many applications.
