Product Description

General Introduction:
The band-pass filter is a filter with cutoff bands on both sides of the transmission band of the spectral characteristic curve. According to the spectral characteristics, the band-pass filter can be roughly divided into broadband filter and narrow-band filter. The two filters are usually combined. The principle of light wave interference is applied to prepare band-pass filter, and the band-pass filter has been widely used in various fields.
