For wavelengths in the mid-infrared (>4 µm), these materials can become absorptive; however, we note from Fig. 2 that a 3,000 K tungsten emitter radiates a very small fraction of light (∼ 3.8% ...

Thermal imaging uses long-wave infrared radiation (LWIR), which has wavelengths ranging from 8-14 micrometers. (1 micrometer = 0.0001 cm = 0.000001 meters). Photo credit: Wikimedia Commons.

Electromagnetic radiation with a wavelength longer than about 700 nanometers won't activate rhodopsin, ... essentially a temperature sensor - to detect infrared radiation.

Electromagnetic radiation with a wavelength longer than about 700 nanometers won't activate ... The mosquito then uses TRPA1—essentially a temperature sensor—to detect infrared radiation.

At high power, near-infrared wavelengths can damage the human eye, and they are hampered by atmospheric scattering and absorption. Razeghi, who leads Northwestern’s Center for Quantum Devices, has ...

The cosmic background radiation currently emits mainly at microwave wavelengths; its radiation intensity peaks at a wavelength of approximately 2 millimeters (about 0.1 inch).

Williamson Corporation's Pro 100 and Pro 200 Series multi-wavelength infrared temperature sensors are ideal for a multitude of industrial applications where devices such as thermocouples and RTDs ...
