Bandpass filters are designed to isolate a region of the UV,visible,infrared spectrum. This is accomplished using a complex process of constructive and destructive interference.Band pass filters have bandwidths (measured at half-peak transmittance levels) less than 6% of the center of wavelength value.Our bandpass optical filters and narrow bandpass filters are coating on transparent optical glass or colored optical glass.Default AOI is 0°.FWHM is full width at half maximum.CWL means center wavelength
