Infrared LED


Peak emission wavelength: 3.9 μm


The L15894-0390ML is a mid-infrared LED with the peak emission wavelength 3.9 μm respectively. This product has been created using Hamamatsu unique crystal growth technology and process technology. It has narrow directivity and increased output because it has a reflector. This is suitable as light sources mounted in gas detectors.

- High output
- High-speed response
- High reliability
- Low power consumption
- TO-46 with reflector (for light condensing)
