What is typical application for 470nm bandpass filters?
Typical application for 470nm bandpass filters is very broad, include fluorescence microscopy and flow cytometry, biomedical diagnostics and sensing, machine vision and industrial inspection, environmental monitoring and oceanography, spectroscopy and analytical chemistry…etc.
What is key parameter when choose for a suitable bandpass filters?
When selecting a bandpass filters, the center wavelength (CWL) will be one of key parameter to be designated, with a tolerance of generally +/-5nm or +/7nm which depend on the user inquiry. Secondly, Full Width at Half Maximum(FWHM) means the transmittance range, for those FWHM is short, normally called narrow bandpass filters which no united definition and typically for lower than 10nm. then, Peak and Average Transmittance,e.g 90%,95%…etc. higher transmittance might need Anti-reflective(AR) coating.
