A Fabry-Pérot etalon for optical filtering and generation of interference rings in the normal Zeeman effect experiment.

The fixed etalon consists of a substrate with a double-sided, partially reflective mirror coating of high reflectivity. The substrate and mirrors form an optical resonator which fulfils the resonance conditions of the red cadmium line (λ = 644 nm).
The tilt of the etalon to the optical axis can be adjusted with three adjustment screws in the housing, allowing the displayed pattern of interference rings to be shifted horizontally and vertically.


Wavelength range: 644 nm
Substrate material: Suprasil
Refractive index: 1,4567
Coefficient of reflection: 0,85
Flatness: 32 nm (λ/20)
Aperture: 22 mm
External diameter: 130 mm
Diameter of rod: 10 mm
Height from end of rod to optical axis: 150 mm
