infrared light emitting diodes photodiodes

Mid-infrared LEDs possess certain competitive advantages:

✔ Low power consumption, compact size & low cost – ability to design autonomous wireless sensors (as a part of remotedly controlled systems)
✔ Long lifetime & no need in frequent calibration – cutting system maintenance costs (DCV, HVAC systems)
✔ Short response time – ability to analyse objects requiring immediate attention (plastic/paper during fabrication; medical applications)
✔ Multielement LED design & scalability – ability to arrange multiwavelength emitters and compact cost-effective LED spectrometers on their basis
