Midwest Optical BP470-49

Description

BP470 filter enhance viewing of subjects illuminated by blue LED lighting and any UV-excited blue fluorescence emissions (430-500 nm). 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.

• Useful Range: 425 to 495 nm
• FWHM: 85 nm
• Tolerance: +/- 10 nm
• Minimum Peak Transmission: >90%
• Surface Quality: 40/20
• Compatible LED: 450 nm, 465 nm, 470 nm

85% of all industrial UV fluorescence applications involve imaging a blue fluorescence. Use of a BP470 or similar blue bandpass filter is almost mandatory in order to obtain adequate contrast.
