Etude et conception d'une lentille à focale variable

Abstract

This final year project primarily aims to explore the theoretical and practical aspects ofdesigningandcreatinganinnovativeliquidlenswithavariablefocallength,capableofmeetingspecific needs (zoom, microscope lens, telescope lens, variable magnification optical systems,etc.).

In the first part, we undertook the design and fabrication of a robust and precisemechanical structure intended to hold the liquid lens in place, ensuring pressure on the lensthrough a mechanical mechanism responsible for the variation of the focal length. For thispurpose,weused SolidWorkssoftware.
