[edit]

This technology image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with

It is recommended to name the SVG file “Focalisation miroir.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
| Description |
Focalisation de rayons parallèles par une miroir parabolique. La figure de gauche montre que la focalisation est imparfaite, les rayons non parallèles à l'axe ne se coupent pas tous au même point. La figure de droite montre de manière caricaturale la focalisation approché dans les hypothèses de Gauss.
