Bandwidth Calculation (Spectral Transmittance)
Bandwidth Calculation (Spectral
Transmittance)
Bandwidth is calculated using the following equation:
Where
b is the bandwidth at X dB,
λ
N
is the nominal wavelength,
λ
XdBLeft
is the wavelength on the left at which the power is X dB below
the power at the nominal wavelength.
λ
XdbRight
is the wavelength on the right at which the power is X dB
below the power at the nominal wavelength.
