Through the length of the spectrum (i.e. the region where the spectrum is located), the filter is divided into: UV filter, visible filter, near-infrared filter, medium infrared filter and far-infrared filter.
Spectral wavelength range:
UV filter 180 ~ 400nm
Visible light filter 400 ~ 700nm
Near infrared filter 700 ~ 3000Nm
Infrared filter above 3000Nm ~ 10um
