Students kit Optics 2.0

Explore light rays and optical phenomena through hands-on experiments

School level: Secondary education
Number of students: 2–3 students
Use: Student experiments in one working group

The Students Kit Optics 2.0 provides comprehensive experimental materials covering key topics in ray optics. The RiSu-certified student light source can be switched between LED and laser, enabling experiments on ray paths as well as image formation on the optical bench. Thanks to the powerful light source, many experiments can also be carried out in rooms that are not darkened.

The rotatable measuring table with angular scale allows angles of incidence and reflection to be read directly. A 50 cm optical bench and the universal mirror provide further options for a variety of experimental setups. In addition to reflection and refraction, experiments can cover total internal reflection, focal points and image formation with lenses, spectral colours and Fermat’s principle.

For further experiments on wave optics, the Students kit Optics 2.0 can be expanded with the supplementary set. Space for the additional components is already provided in the storage box of the optics set.

With the laser and the LED of the student lamp as well as the associated worksheet, the formation of shadows as a stitching optics is investigated.


The law of reflection is discovered with the laser of the student lamp on the measuring table.


The reflection of a parallel beam of light is reflected convex spherically, concavely spherically and concave parabolically on the surfaces. The test is carried out as a stitching optics.


The transition of light from air to glass is investigated. Snellius's law of refraction is discovered and the refractive index of air in glass is determined experimentally.


The transition of light from water to air is investigated. The refractive index of water and the limit angle of the total reflection are determined.


In two partial tests, the focal points of a cut-collecting lens with the stitching optics are first determined. The focal point of a lens on the optical bench is then measured.
