Optics System 1 - code: 4864.19

A complete system to study the principal laws of geometric optics. The Optics System 1 can be used for the study of many aspects of geometric optics, including photometry, luminous intensity, focal length of a lens and many other experiment.

Experiments
Thin lens equation

If the converging lens has a focal length such that the system of the converging plus diverging lenses is still converging, it is possible to recover the focal length of the system by using the thin lens equation (valid in the “Gauss approximation”).
