Fabry-Perot-Etalon 508 nm - 644 nm

Fabry-Perot-Etalon 508 nm - 644 nm, 1022359, Fundamentals of Atomic Physics
For optical filtering and generation of interference rings in the experiment to demonstrate the Zeeman effect.

The fixed etalon (broadband) 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 for a specific wavelength range of 508nm - 644 nm of the red cadmium lines of interest. 
The inclination of the etalon to the optical axis can be adjusted by means of adjustment screws in the frame, allowing the pattern of the interference rings to be shifted both horizontally and vertically.

Wavelength range: 508 nm - 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
