Main Question or Discussion Point
i want to know about wave length of infarade wave and working range
what??? makes no sense.is the wavelength of light the frequency that it sends out photons?
Typically, short-wave infrared (SWIR) is from 0.7 um to 1.1 um, the part of the spectrum we can't see but that Si detectors can still respond to. Mid-wave (MWIR) is about 3-5 um and long-wave (LWIR) is 8-12 um: both bands are set by absorbance bands of water, and the MWIR and LWIR bands are within 'transmission windows'. Going out further, for example in FTIR measurements, the far infrared can go out to about 20um or more.i want to know about wave length of infarade wave and working range
