The short wave ir band refers to the wavelengths between 1000-3000 nanometers, and these spectra cannot be recognized by the naked eye. Minerals, man-made substances, and some other living things have special components that SWIR can "see".

Fixed focal length SWIR lens, image size 1, Φ16.4mm, F-Number 1.4, and the working wavelength is 700-1700nm, which matches the vast majority of area array short-wave near-infrared (NIR) cameras. Large aperture design, suitable for low illumination environment.

Zoom SWIR lens, the working wavelength is 900-1700nm, compatible with most area array short-wave infrared (SWIR) cameras. Long focal length design, suitable for long distance observation.

Advantages of infrared technology The region of short wave infrared wavelength is 1400-3000 nanometers, and the naked eyes cannot recognize these spectrum.
