Red LED

Red LEDs have a peak emission wavelength in the 660 to 700 nm range. They are used in a wide range of applications including optical switches, POF data communication, and barcode readers. Various types are available including a type with a reflector (cavity) on the metal base to increase the irradiance, a type with lens featuring narrow directivity, and a type that can irradiate over a wide range without a reflector.
