Converts a Spectral Bandwidth to Frequency Domain


This calculator will help you convert a spectral bandwidth expressed in wavelength Δλ at a certain central wavelength λ₀ to the frequency domain.

The formulas that will be used are as follows:

C = 3 × 108 m/s

V₀ = C / λ₀

Vstart = C / (λ₀ + Δλ / 2)      Vstop = C / (λ₀ - Δλ / 2)

ΔV = Vstop - Vstart

Where: Wavelength Bandwidth Δλ; Center Wavelength λ₀; Center Frequency V₀; Frequency Bandwidth ΔV.
