Abstract
In this work we study an alternative and innovative method for the manufacture of polymeric micro-lenses and how the characterization of its physical, mechanical and optical parameters is relevant for their application. We study the equilibrium shapes of drops that emerge slowly from vertical thick-walled tubes, as a result, it is found that the sizes and shapes of drops depend on the Bond number, the injection pressure and the value of the contact angle, so that finally with this technique we are able to make lenses. The manufacture will be made though drip injection since it is easier to control the shape of the lens.
