Narrow Bandpass Filter

Name: Narrow Bandpass Filter
Brand: ECOPTIK INDUSTRIAL PTE.LTD.

Narrowband filter is a special type of bandpass filter, but its performance requirements are more extreme and precise. It only allows light within a very narrow wavelength range to pass through, while strongly blocking all light outside of that range. Applied to fluorescence microscopy, astrophotography, Raman spectroscopy, flow cytometry, fluorescence detection and biosensing, laser cleaning and fluorescence excitation.

Features of Narrow Bandpass Filter

Bandwidth refers to the distance between two positions in the passband whose transmittance is half of the peak transmittanceThe above six parameters must be taken into account in the use and selection of narrow-band filters. Different performance indexes require different manufacturing costs of filters.
