The visible light spectrum that humans perceive spans only a small portion of the electromagnetic spectrum — roughly 430 to 750 THz, corresponding to wavelengths of ~400-700 nm. Just beyond this range ...

Researchers have developed a new 'cooler' sensing instrument thereby increasing energy, efficiency and enhancing mobility for diagnostic testing. The new portable, field-friendly, mid-infrared ...

A researcher has developed a new technique to detect long wave infrared (LWIR) photons of different wavelengths or 'colors.' The new detection and imaging technique will have applications in analyzing ...
