1550nm fiber lasers used in these applications are pumped by diode lasers that emit in the 900nm band
and/or air quality that affect uncoated IR filters
It's designed to isolate dark red wavelengths while blocking out-of-band light
The Bi940 features a much narrower band design compared to the BN940
Blue Bandpass Filter, 425-495nm - MidOpt BP470 Longpass 1550nm fiber lasers used inThe MidOpt BP470 Blue Bandpass Filter enhances the viewing of subjects illuminated by blue LED lighting and any ultraviolet (UV) excited blue fluorescence emissions (430 500nm). Its broad bandwidth and high peak (T 90%) transmission results in significantly brighter, higher contrast images. For most machine vision UV fluorescence applications, use of a BP470 filter is absolutely necessary. The StablEDGE design prevents unwanted interference from
