Narrowband filters are defined as bandpasses with a very small passband width, generally within 30nm. Because of its large cut-off depth outside the passband band, it has a good signal-to-noise ratio. The transmittance zone can cover the near-ultraviolet, visible and near-infrared regions. The main application scope of the products is: astronomical photography, biochemical analysis, medical detection, laser spectral line separation and ranging, machine vision, etc.
