Spectral transmittance requirements. The green lines are the straight-line fits. The annotations on the plot are defined below:
λS= 380nm. λS is the straight-line fit intersection with the wavelength axis for T values between 10% and 80% (on the short wavelength side).
λL= 648nm. λL is the straight-line fit intersection with the wavelength axis for T values between 90% and 20% (on the long wavelength side).
Minimum ∆PB: 225nm. ∆PB is the spectral width of the pass band.
T > 80% min. @400-420nm.
T > 85% min. @420-600nm, with the average T >90% in this pass band.
T < 5% @ 685nm.
T < 3% @700nm.
Average T < 1% between 750-1100nm.
Maximum T <3% between 750-1100nm.
Average T < 1% between 300-380nm.
Maximum T <3% between 300-380nm.
Incident angle: 0 degree.
