What is an infrared filter? What instruments are they used on?

Infrared filters, as a specially designed optical device, allow infrared light within a specific wavelength range to pass through while blocking other wavelengths of light, especially visible light and ultraviolet light. The working principle of this filter is based on the selective absorption and transmission…
