converts a spectral bandwidth to frequency domain

This calculator will help you converts a spectral bandwidth expressed in wavelength Δλ at a certain central wavelength λ0to frequency domain.

The formula that will be used is as followed:

C=3*10$^8$

$V_0$= $\frac{C}{\lambda_0}$

$V_{start}$ = $\frac{C}{\lambda_0 + \lambda/2}$      $V_{stop}$ = $\frac{C}{\lambda_0 - \lambda/2}$

$\triangle V$= $V_{stop}$ - $V_{start}$

Wavelength Bandwidth $\lambda$; Center Wavelength $\lambda_0$;
Center Frequency $V_0$; Frequency Bandwidith $\triangle V$;
