Data sheet Fabry Perot interferometer

Description

The Fabry-Pérot is an optical interferometer which has the advantage of having a significantly higher fineness that the other interferometers, in particular with regard to a Michelson interferometer that only has a finesse of 2.

Thus, this allows a far more accurate measurement of wavelengths and a sufficiently high resolution to separate very close lines such as the sodium doublet.

Applications:

- Highlighting the multiple reflections
- Measuring the fineness of the cavity and the resolution power
- Separating the very close wavelengths (Sodium doublet)
- Measuring the quality coefficient
