NIRsäteilyllä
NIRsäteilyllä refers to near-infrared radiation. This is a portion of the electromagnetic spectrum with wavelengths longer than visible light but shorter than infrared light. The typical wavelength range for near-infrared radiation is from approximately 700 nanometers (nm) to 2,500 nm. It is invisible to the human eye, unlike visible light.
Near-infrared radiation has various applications due to its specific properties. In spectroscopy, it is used for
In telecommunications, near-infrared light is employed in fiber optics for transmitting data. Its lower attenuation in
Other applications include thermal imaging, where certain sensors can detect heat signatures by measuring emitted near-infrared
