Infrared radiation is quite broad and can essentially be broken down in various ways using wavelength ranges. One such manner breaks them down into the following five sub-categories of interest:
- Near Infrared (NIR) - from 750 nm to 950 nm
- Near Infrared (NIR) - from 950 nm to 1.4 µm
- Near Infrared (NIR) - from 1.1 µm to 2.5 µm
- Mid Infrared (MIR) - from 2.0 µm to 5.0 µm
- Far Infrared (FIR) - from 5.0 µm to 15.0 µm
The total range of infrared radiation can actually to out as far as 300 µm. It has multiple applications, from eye-safe range finding to thermal imaging and night vision, and is invisible to the human eye.
Excelitas offers various sensors that can detect Far Infrared (FIR) light, from single or dual channel thermopiles for gas detection to digital pyroelectric detectors for advanced motion detection applications.
Excelitas is a leading supplier of optoelectronic sensors and modules that covers the entire electromagnetic spectrum, from Gamma rays all the way to the Far Infrared. Whether you are looking at visible photons for fluorescence measurements, long-wavelength infrared for motion sensing, gamma rays for nuclear medicine, or anything in-between, chances are we have the detector you are looking for.

Infrared light can be used to look through paintings to see the artist’s original outline drawing made with a pencil, for instance.
