Complete Kit for Learning Focometry

The Basix Start profile set is designed to introduce students to the principles of optics with quality equipment. The sliders equipped with an indexing mark facilitate precise positioning of the elements, making manipulations clear and reproducible during practical sessions.

Its anodized aluminum profile bench, available in two lengths (2 m and 1.2 m), guarantees robustness and stability, while remaining easy to integrate into school laboratories. This starter set is perfectly suited for exploring focometry and allows for the effective execution of fundamental experiments in middle and high school.

What Educational Experiments Can Be Carried Out Practically?

Image Formation by a Thin Lens

Hands-on activities to understand image formation and fundamental optical relationships.

  • Conjugation Laws: study of the relationship between the object position, image position, and focal length (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 suited for school teaching 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 lens center 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.

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 specialized courses. They allow for a progressive and official curriculum-compliant approach to the concepts of conjugation, focal length, and experimental measurements.
