Mid-wave infrared (MWIR) LED chips emit light in the wavelength range of 3 to 5 micrometers, which is longer than the wavelength of SWIR light and shorter than the wavelength of long-wave infrared (LWIR) light. MWIR LEDs are commonly used in applications such as thermal imaging, gas sensing, and missile tracking.
IR-C LEDs, also known as far-infrared (FIR) LEDs, emit light in the far-infrared range, specifically in the wavelength range of 20 to 350 micrometers. They are typically used for applications such as thermal sensing, temperature measurement, and astronomy.
It is important to note that while MWIR and IR-C LEDs both emit light in the infrared spectrum, they operate in different wavelength ranges and have different applications. MWIR LEDs are used for imaging and sensing applications, while IR-C LEDs are used for temperature measurement and astronomical observation.
