The thermal image sight is the sight that converts the target thermal radiation image into the visible light image. A kind of passive infrared sight. Read More

Infrared optical materials are the components used to prepare lenses, prisms, windows, filters, and other items. Infrared optical materials mainly include semiconductor materials and dielectric materials (mainly alkali halide compounds, oxides, and some inorganic salts). According to their composition and morphology, they can be divided into five categories: crystal, hot-pressed polycrystalline, transparent ceramics, glass, and plastic; According to the transmission band, they can be divided into two categories: medium wave infrared optical materials and long wave infrared optical materials.

Light is an electromagnetic wave with the same nature as radio waves. Generally, infrared light is divided into three parts: near, middle, and far infrared. Near-infrared refers to the wavelength of 0.75~3.0 μ m; middle infrared refers to the wavelength of 3.0~20 microns; Far infrared refers to the Read More

The short-wave infrared band refers to the band with a wavelength between 1400-3000 nm, which cannot be recognized by the naked eye. Minerals, artificial substances, and other ground objects have special components, and short-wave infrared can "see" this special component, but the naked eye and visible light near-infrared light waves are "invisible".
