Spectral Bandwidth ↔ Frequency-Domain Converter

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

V_start = C / (λ₀ + Δλ / 2) V_stop = C / (λ₀ - Δλ / 2)

ΔV = V_stop - V_start

Where: wavelength bandwidth Δλ; center wavelength λ₀; center frequency V₀; frequency bandwidth ΔV.

Input

Center Wavelength, λ₀ (nm):

Wavelength Bandwidth, Δλ (nm):

Output

Center Frequency, V₀ (THz):

THz

Frequency Bandwidth, ΔV (THz):

THz

Spectral Bandwidth → Frequency-Domain Conversion

C = 3 × 108 m/s

V₀ = C / λ₀

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

ΔV = Vstop - Vstart

Center Wavelength, λ₀ (nm):

Wavelength Bandwidth, Δλ (nm):

Center Frequency, V₀ (THz):

Frequency Bandwidth, ΔV (THz):

C = 3 × 10⁸ m/s

V_start = C / (λ₀ + Δλ / 2) V_stop = C / (λ₀ - Δλ / 2)

ΔV = V_stop - V_start
