Optical interferometer 202759

Fabry-Perot

The Fabry-Pérot is an optical interferometer that has the advantage of having a much higher finesse than other interferometers, especially compared to a Michelson interferometer which only has a finesse of 2. This allows for a much more precise measurement of wavelengths and a resolution high enough to separate very close lines such as the Sodium doublet. - Dimensions: H300 x W130 x D210 - Weight: 8kg - Material: aluminum and steel - Optical axis: height 22cm - Mirror diameter: 40mm - Useful diameter: 38mm - Reflection coefficient: greater than 97% - Flatness: Lambda/20 - Mirror adjustment: by 3 screws at 120° - Finesse: greater than 100 - Translation: by micrometric vernier - Displacement: 25mm - Stability: anti-vibration silentbloc feet
