Band-pass filters only transmit a certain wavelength band, and block others. The width of such a filter is expressed in the wavelength range it lets through and can be anything from much less than an Ångström to a few hundred nanometers. Such a filter can be made by combining an Longpass- and an Shortpass filter.
Bandpass Filters are narrowband filters used extensively in applications including flame photometry, elemental or laser line separation, fluorescence, laser diode cleanup, or chemical detection or analysis. Bandpass Filters feature durable hard coatings to minimize filter degradation while increasing transmission. These optical filters offer steep slopes with deep blocking to achieve high performance in demanding applications.
