How FLIR Optical Gas Imaging Cameras Work

We know thermal cameras can see heat, but how are FLIR Optical Gas Imaging Cameras able to see gas? In visible light, gas is completely transmissive - light goes right through the molecules. However, many gases have infrared absorption characteristics that can be targeted with specially designed thermal imaging cameras. Watch this great video on how Optical Gas Imaging Cameras work:
