3.What is typical application for 905nm narrow bandpass filters?
One of the most common narrowband filters at 905nm, and it only allows light within a very narrow band centered at 905nm (such as ±5nm or ±10nm) to pass through, while strongly blocking light of other wavelengths (including visible light and most infrared light).
Its typical applications are almost all around 905nm pulsed laser diodes. and This type of laser is widely used in ranging, radar, and detection fields.
4.What is key parameter when choose for right Narrow bandpass filters:
When selecting a Narrow bandpass filters, the center wavelength (CWL) will be one of key parameter to be designated, with a tolerance of generally +/-3nm or +/5nm 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.
