Description

The experimental device used the 546.1nm spectral line of a mercury lamp as an object to study the Zeeman effect. The spectral line emitted by the mercury lamp passes through the condenser to properly converge the divergent light, passes through the polarizer, and is filtered by the filter to form monochromatic light, enter the FP etalon, and form an interference ring. Finally, the lens and CMOS camera Imaging. The device contains an adjustable constant current power supply, which controls the size of the magnetic field by adjusting the current. When the magnetic field is strong enough, the energy levels begin to split and produce different spectral lines. Each level of interference ring is split into multiple interference rings. Image acquisition and data analysis are performed by professional software to obtain the electron-to-mass ratio e / m Value. When the electromagnetic coil is rotated 90 degrees and the optical path is fine-tuned again, the Zeeman effect can be observed parallel to the direction of the magnetic field.

Compact Design

Using industrial-grade high-strength optical track, work with state-of-the art Optical-mechanics, saved 1/3 of the space than conventional apparatus.

The electromagnetic unit can achieve 0-1.2T uniform magnetic field. And it is rotational in 0-1200 range, This will be used to observe transverse and longitudinal zeeman effect.

Up to 1 / 100λ Fabry - Paros etalon, can achieve 9 splitting lines from K to K-2 K-class

The F-P etalon performance make the splitting line obvious, clear and sharp.

CE certification

Passed the European Union CE safety certification and strictly controlled the quality according to the CE standard.

Typical experiments and data

1， Transverse zeeman effect（Л Line）

2，Longitudinal zeeman effect（σ Line）

3，Calculate e/m based on the nine splitting line of K to K-2 level.

The relative error of e/m result less than 5%.
