Bandpass Fliters are used to selectively transmit a portion of the spectrum while rejecting all other wavelengths. Optical Bandpass Filters are ideal for a variety of applications, such as fluorescence microscopy, spectroscopy, clinical chemistry, or imaging. These filters are typically used in the biochemistry,detection instrument and telecom optical components.gallery-eo offers a wide variety of Optical Bandpass Filters in a range of bandwidth options which have advantage as follow: narrow transition band, high transmittance , deep cut-off area.
