Interference filter wheel

A versatile support for the study of light spectra

The interferential filter wheel is designed to facilitate the selective observation of spectral lines during high school physics practical work. It allows for clear and reproducible experiments on the decomposition and analysis of light emitted by different sources.

The turret component holder offers simple handling and quick filter changes. Each interferential filter is centered on a specific wavelength, corresponding to the characteristic lines of Mercury and Sodium.

This device enables teachers to highlight the characteristic emission lines and concretely illustrate the fine structure of light spectra. It easily integrates into spectroscopy experiments and serves as a suitable tool for demonstrations and supervised classroom activities.
