One of the coolest things about infrared cameras ... toward the visible spectrum. So for something at room temperature (like 300 Kelvin), this peak wavelength is about 9.7 μm (micrometers).

Sensor Unlimited has introduced Visible-InGaAs ... world's smallest dual wavelength-range camera that simultaneously images in the visible and short-wave infrared spectrum. The SU320Mvis 1.7RT ...

In a new study published in Science, researchers have developed a new method for detecting infrared light by changing its frequency to a corresponding frequency in the range of visible light.

The end result is a high resolution image sensor that's sensitive to a huge range of wavelengths, from UV rays of about 300 nm, through the visible spectrum in the middle, and up to infrared light ...
