When the students focus the telescope model on a relatively distant object in the second part of the experiment, it is advisable for them to hold it with one hand and to focus with the other. To avoid damage to the lenses, the teacher should have the students attach the parts of the optical bench as tightly as possible and to handle the lenses carefully. The use of a diaphragm to limit the field of vision was avoided so that the model and the experiment with it could be made as simple as possible.


  • Multifunctional light box - All-in-one: Can be used for geometric optics on the table, colour mixing and on an optical bench
  • Extension with others sets at anytime, no additional light sources needed, recognition value for students


How is an astronomical telescope constructed and how does it work? Construct a model of an astronomical telescope and investigate how its parts interact.
