Spectral Bandwidth → Frequency-Domain Conversion


This calculator converts a wavelength-domain spectral bandwidth Δλ at a given center wavelength λ₀ into the frequency domain.

The formulas used are:

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.
