WebShort Wave IR (SWIR) is a subset of the infrared band in the electromagnetic spectrum, covering the wavelengths ranging from 1.4 to 3 microns. This wavelength is not visible to human eyes and as a result can often offer a better image than what is achievable with visible light imaging. WebNear Infrared (NIR) is a subset of the infrared band of the electromagnetic spectrum, covering the wavelengths ranging from 0.7 to 1.4 microns. This wavelength is just outside the range of what humans can see and can sometimes offers clearer details than what is achievable with visible light imaging. NIR is very close to human vision but ...
WebJun 29, 2024 · The main ranges for non-contact temperature measurement are the NIR, SWIR, MWIR and LWIR ranges covering wavelengths of 0.75 - 15 μm. It is therefore called “Thermal Infrared”.
