    What does a IR-cut Filter do?

            The wavelength range of visible light that the human eye can feel is generally 380~700nm.         There is also near-infrared light in nature that cannot be seen by human eyes. At night, this light still exists. Although it cannot be seen by human eyes, it can be captured by using CMOS se...

  • What is the Distance Range of the Thermal (Infrared) Camera

    What is the Distance Range of the Thermal (Infrared) Camera

    When purchasing an infrared camera, users often ask a question: how far can the infrared thermal camera I purchased see? Or should I identify a thermal imager with what parameters a person should choose at 500 meters? In fact, this is a particularly important but difficult issue to clarify. For e...

  • What is NIR/SWIR/MWIR/LWIR/FIR Spectral Range?

    What is NIR/SWIR/MWIR/LWIR/FIR Spectral Range?

    Herschel was the first person to discover the existence of infrared ray. As early as February 1800, he used prism to study the visible spectrum. Herschel found that he could put the thermometer outside the red end of the spectrum and detected unknown invisible spectra, which were hotter than any ...
