The new infrared green laser pointer “sniffs” trace chemicals. According to a consultation report, a new prototype of a chemical sensor was able to detect “fingerprint traces” of chemicals and other substances from a distance of 100 feet, and its developers are working to reduce its size to the size of a shoe box.
The device is expected to identify trace amounts of drugs and explosives and speed up the analysis of certain medical samples. This portable infrared chemical sensor can be mounted on drones or carried by users such as doctors, police, border officers and soldiers. The device’s sensor is based on a new type of fiber laser that combines high power with a laser beam that covers a wide infrared frequency range (from 1.6 to 12 microns, covering the mid-wave and long-wave infrared bands).
Researchers demonstrate this prototype chemical sensor. The researchers who developed this laser stated that most chemicals have characteristic fingerprint absorption peaks between 2 and 11 microns, so this wavelength range is called the ‘spectral fingerprint region’, and our green laser pointer device can Characteristic absorption peaks identify solid, liquid, and gas target substances.
