Narrow Bandpass Filters
PRODUCT CATEGORIES
Narrow band filter is subdivided from the band-pass filter, and its definition is the same as that of the band-pass filter, that is, this filter allows optical signals to pass through a specific band, while the optical signals on both sides that deviate from this band are blocked. The pass band of the narrow-band filter is relatively narrow, generally less than 5% of the central wavelength value.
