Presentation

Basix Dual Clix Profile Composition – The Perfect Alignment for Optical Experiments

The Basix Dual Clix composition is designed to facilitate optical manipulations in educational settings, from middle school to high school. Its new version with H60 column carriers ensures that all components of the bench are at the same height, simplifying optical alignment during practical work.

Thanks to the robustness of the materials and the quality of the Clix system, this kit allows for quick and efficient adjustment of elements, reducing setup time to maximize experimentation time. Teachers thus benefit from a reliable and simple tool, perfectly suited for learning the fundamental principles of geometric optics.

What Educational Experiments Can Be Conducted Practically?

Image Formation by a Thin Lens

Practical activities to understand image formation and fundamental optical relationships.

Conjugation laws: study of the relationship between the object position, image position, and focal distance (application of conjugation equations).
Experimental demonstration: observation of the position and size of the image depending on the object–lens distance (concepts of real/virtual image, upright/inverted image, and magnification).

Determination of the Focal Length of a Converging Lens

Several experimental methods adapted to school teachings and practical sessions.

Autocollimation method: a converging lens is placed against a plane mirror to obtain a sharp image of the same size as the object but inverted. With this method, the focal length of the lens corresponds to the distance between the center of the lens and its image.
Bessel method: use of two symmetrical lens positions producing a sharp image; the difference in positions allows calculation of the focal length.
Silbermann method: a particular case of the Bessel method also called the 2f-2f method.

Study of Diffraction by a Slit

Observation of a laser beam passing through a narrow slit to demonstrate the diffraction phenomenon.

Width of the central maximum: visualization of the diffraction pattern on a screen and measurement of the central maximum width depending on the slit width.
Influence of slit width: comparison of patterns obtained with different slits.
Influence of wavelength: comparison of patterns obtained with different monochromatic sources to show the relationship between λ and the pattern width.

Study of Interference by a Double Slit

Experiments highlighting the superposition of two coherent light waves from the same source, illustrating the wave nature of light.

Interference fringes: observation of fringes on a screen, measurement of fringe spacing.
Wavelength determination: use of fringe measurements to calculate the wavelength of a laser source.
Young’s slits vs. asymmetric double slits: comparison of patterns obtained with two identical slits (regular and symmetric interference) and with slits of different widths (intensity modulation and fringe asymmetry).

Is This Product Suitable for the High School Physics Curriculum?

Yes. The proposed manipulations and protocols (image formation by thin lens, focal length determination by autocollimation, Bessel method, and Silbermann method) directly align with the educational objectives of science teaching in high school—from 10th grade to 12th grade specialization. They allow for a progressive approach to the concepts of conjugation, focal length, and experimental measurements in accordance with official expectations.
