Description
Product Description:A negative filter is a notch filter, also commonly called a band-stop or band-suppression filter, which means that the light with a cut-off characteristic of a given wavelength can transmit as much spectrum as possible in the remaining wavelength bands, and the spectral characteristics are concave. shaped filter. It is a relatively cut-off filter, which is mainly used to eliminate or reduce specific light and enhance other spectral energy. The cut-off depth and the flatness of the transmission area are the key measurement parameters of the index.
