"LWIR" yog cov lus luv luv rau "Long Wave Infrared", nws nyob ntawm qhov pom tsis pom ntawm lub tshuab hluav taws xob, lossis tshwj xeeb tshaj yog, lub spectrum infrared, thiab muaj lub wavelength ntawm 8μm ~ 14μm. LWIR koob yees duab thiab sensors, nyob rau hauv ib tug yooj yim rundown, yog tsim los ntes thiab ntes infrared tawg, uas yog unseeable rau lub liab qab tib neeg lub qhov muag, nyob rau hauv lub IR band.
Ntev-yoj Infrared muaj ntau zaus qis thiab nqa lub zog tsawg dua li pom lub teeb, thiab tsis muaj teeb meem li ultraviolet lossis X rays:
LWIR koob yees duab feem ntau yog siv rau hauv thermal imaging thiab kev ruaj ntseg daim ntaub ntawv xws li leakage/gas detection, heating/cooling inspection, chemical/aerial/medical thermography, non-contact material testing, etc.
