Etude et conception d'un objectif fisheye

Abstract

The Fish-Eye lens is a lens that stands out from the others for its ability to take pictures with a wide angle of view (almost 180° diagonally), which is why it is very popular with photo enthusiasts. Unfortunately, this ability to take large photos is also accompanied by certain defects: fairly significant distortion, chromatic aberrations, as well as other optical phenomena that can be annoying when you want to obtain a high-quality image. It is therefore necessary to correct these errors to obtain an image pleasing to the eye, this is the main objective of this work. In this work, by exploiting the functions of the optical design software of the company Zemax (OpticStudio), we want to redo the design of a Fisheye-Nikkor 10.5 mm f/2.8G ED lens, consisting of 10 lenses, including the is to reduce the number of lenses while preserving as much as possible the Optomechanical characteristics of the lens such as focal length, length, type of lenses used, better image quality, fewer aberrations, an RMS, MTF and a Spot Diagram within an acceptable range from the lens of the Japanese company Nikon.
