| Titolo: | Galileo and optical aberrations / Yaakov Zik. |
| Abstract: | An image-forming system is complex not only because of elements such as tubes, lenses and diaphragms, but also because each element is placed there for a specific function. Magnification should not be the primary factor by which the performance of the refractor telescope is evaluated. Too many nonlinear variables such as field angle, lens quality, light gathering, corrections for the various aberrations, and losses in light transmission through the optical system are also involved in the construction of the telescope. Evidently, an astronomical telescope capable of yielding a reasonable magnified image of a bright star could not have been constructed by chance. In this light it is instructive to see how Galileo described, analyzed and resolved the adverse effects caused by the various optical aberrations while refining his telescope |
