Optical BandPass Filter
CWL:Center Wavelength of bandpass filter
Tmax:transmittance of center wavelength
FWHM(full width at half of Tmax): indicates the spectral width at which the signal has fallen to 50% of the peak value.
Cut-on wavelength: the wavelength at which a long pass filter transmits 50%
Cut-off wavelength: the wavelength at which a short pass filter transmits 50%
Angel of Incidence:0 degree.
The passband shifts to blue and becomes worse when a filter is illuminated by a focussed beam or at an angle by a collimated beam.
The blue shift is caused by the reduction of the difference in path length between the transmitted and reflected beams.
