Chemical compounds all carry distinctive absorption "fingerprints" within the mid-infrared spectral region of 2 to 12 microns. This offers an opportunity to measure and study chemicals at extremely ...

The human eye can only see light at certain frequencies (called the visible spectrum), the lowest of which constitutes red light. Infrared light, which we can’t see, has an even lower frequency than ...
