Large-Format, Narrow Band Pass Filters (NBPF) – A Uniformity Challenge
1/27/2017
Within so many diverse optical filtering applications, large-format (>100 mm diameter), narrow bandpass filters (NBPF) are required to be used alongside large collection optics in order to facilitate specific and selective analysis of a phenomena or the substance of interest.

How To Specify A Filter
In general, typical filter optical specifications will include the wavelength ranges over which to reflect and transmit light, clear aperture of the filter, the polarization state of light for non-normal angles of incidence, light coherency (laser or white light), optical beam size and cone angle of light, and more.
