CWL:center wavelength
Tmax:transmittance of center wavelength
FWHM:full width where transmittance is half of Tmax
According to filter's FWHM, Bandpass filter can be
NBPF(narrow bandpass filter) BP (bandpass filter)and WBP(wide bandpass filter)
Usually BP filter is used in analytical instruments, such as Biomedical, Fluorescence and Biochemical instruments.
By its pass band widths it can be named as Narrow Band pass filter,Middle Band pass filter.
