Central Wavelength Calculation (Spectral Transmittance)

Central Wavelength Calculation (Spectral

Transmittance)

The central wavelength is calculated using the following equation:

a is the central wavelength,

is the wavelength on the right at which the power is 3 dB below the

power at the nominal wavelength, and

is the wavelength on the left at which the power is 3 dB below the

power at the nominal wavelength.
