Narrow Band Filter Wavelength and Transmission

Narrow band filters are used for measuring lamp output at the major mercury excitation lines or for any application requiring an extremely narrow bandwidth.

Our nomenclature for identifying narrow band filters is NSXXX/xx, where 'XXX' represents the wavelength available and 'xx' represents the percentage transmission at center wavelength.
