Photonics Wavelength Converters

Wavelength/Frequency/Electron Volt/Wavenumber Converter

Just enter the wavelength in nanometers and the converter will return Frequency (THz), Energy (eV), and Wavenumber (cm-1)

Enter Wavelength: nm

For the given Wavelength of nm


Frequency: THz
eV: eV
Wavenumber: cm-1

Milliwatts/dBm Converter

Enter the power in mW or the power in dBm, and the converter will return the power in dBm or mW.

Power in mW
or
Power in dBm

mW is equivalent to dBm

dBm is equivalent to mW

Note: in most applications, 3 dBm is assumed to be 2 mW although 2 mW is actually 3.0103 dBm.

Etalon Calculator

To calculate the FSR (in GHz) and Finesse of a solid etalon, please input the following parameters:

Refractive index
Thickness (mm)
Surface reflectivity (%)

FSR =
Finesse =


Or, to find the thickness and reflectivity for a given FSR (in GHz) and Finesse, please input the following parameters:

Refractive index
FSR (in GHz)
Finesse

Thickness (in mm) =
Reflectivity (%) =
