Long-wave infrared (LWIR) refers to a region of the electromagnetic spectrum with wavelengths generally ranging from about 8 to 15 micrometers. LWIR radiation is often used in various applications such as thermal imaging, night vision, gas detection, and remote sensing. LWIR sensors can detect heat signatures and temperature variations, making them valuable tools in military, surveillance, medical, and environmental monitoring applications. Research in the LWIR field focuses on improving sensor technology, developing new imaging techniques, and exploring novel applications for this type of radiation. Overall, LWIR research plays a crucial role in advancing infrared technology and expanding its capabilities in diverse fields.
