Interference filter Ø25.4 mm

A Ø25.4 mm Interference Filter for the Study of Light Spectra

The Ø25.4 mm interference filter is designed to isolate a precise wavelength among several or to transform a continuous spectrum into a quasi-monochromatic source. It is a suitable tool for high school physics practical work, allowing students to more clearly visualize and analyze phenomena related to the decomposition of light.

With a diameter of 25.4 mm and a thickness of 6.3 mm, this multilayer glass filter offers a minimum transmission of 45%. Its bandwidth is 10 nm (FWHM) with an accuracy of 2 nm, ensuring selectivity and reliability suitable for educational experiments.

Used with an appropriate light source, this filter facilitates the highlighting of emission or absorption spectra and easily integrates into educational spectroscopy setups.
