Infrared optical lenses are specialized optical lenses designed specifically for receiving, focusing, and processing infrared wavelengths (typically referring to electromagnetic waves with wavelengths ranging from 0.76 1/m m to 1000 m). They differ fundamentally from the visible light lenses we are familiar with (such as camera and mobile phone lenses) in terms of design, materials, and working principles. Their core task is to efficiently transmit infrared radiation and form high-quality images.
In simple terms, it is an "eye" that enables "infrared cameras" to discern the temperature and outline of objects.
