WebApr 21, 2024 · It’s called a “Full Spectrum” conversion, because now the camera “sees,” and can record, visible, infrared and ultraviolet light. The process involves removing the factory filter covering the sensor and replacing it with what is essentially clear glass. WebThe quantum-well infrared photodetector (QWIP), another type of sensor, is narrow by nature, typically having a spectral range of about 1 µm. This range and its peak wavelength are dependent on the QWIP’s physical …

Infrared radiation is generally considered to begin with wavelengths longer than visible by the human eye. However there is no hard wavelength limit to what is visible, as the eye's sensitivity decreases rapidly but smoothly, for wavelengths exceeding about 700 nm. See more Infrared (sometimes called infrared light and IR) is electromagnetic radiation (EMR) with wavelengths longer than those of visible light and shorter than radio waves. It is therefore invisible to the human eye. IR is generally … See more In general, objects emit infrared radiation across a spectrum of wavelengths, but sometimes only a limited region of the spectrum is of interest because sensors usually collect … See more Night vision Infrared is used in night vision equipment when there is insufficient visible light to see. Night vision devices operate … See more There is no universally accepted definition of the range of infrared radiation.
