Narrow-band filters are subdivided from band-pass filters and are defined in the same way as band-pass filters, that is, the filter allows an optical signal to pass through a certain band while the optical signals on either side are prevented from deviating from this band. The pass band of narrow-band filters is relatively narrow, generally less than 5% of the central wavelength.Our company adopts IAD all-medium hard film coating technology and medium interference principle to produce, which is more stable and high-quality in terms of product performance and quality.At the same time, we will adjust our parameters according to customers' application fields, so that customers' products are more stable and their service life is longer.

Application: fluorescence analyzer, labeling analyzer, breast milk analyzer, license plate recognition, bar code scanning, infrared electronic white board, infrared camera, infrared touch screen, iris recognition, infrared medical instrument, infrared ink recognition, red film recognition, face recognition sensor system.Hand-held infrared laser rangefinder, laser rangefinder, optical instrument, medical and health equipment and testing instruments, etc.
