Infrared LED Elements for NDIR Gas Sensing

AKM's infrared LEDs utilize the semiconductor thin film epitaxial growth technology accumulated through manufacturing of magnetic sensors, which achieves emission wavelength control optimized for the gas absorption wavelength band and high-speed, high-output emission control.

Our own compact molded resin packaging technology contributes to the downsizing of gas sensors as the world's smallest class Surface Mounted Devices (SMD) infrared LEDs.
