Clix ring paired slots and wires token

A Practical Tool for Exploring Babinet's Principle in the Classroom

The paired slits and wires token on a Clix ring allows for a simple visualization of the effect of slit or wire width on the diffraction pattern. Its design also facilitates the experimental demonstration of Babinet's principle by comparing complementary objects arranged in pairs.

This component includes 6 pairs of slits and wires, with identical widths ranging from 35 to 200 µm. Each element is etched with a precision of ±2 µm on an optical glass disc, using a chromium mask deposited through microlithography. The radial layout enables quick alignment and configuration changes without disturbing the setup.

Mounted on a magnetic Clix ring, the token is protected from repeated handling while remaining easy to use. It is a suitable tool for diffraction lab work in high school, particularly for studies of symmetry and complementarity of diffracting objects.
