- Abstract
- Ink-jet printing technique allows locally and preciselydispensing materials for the manufacturing of microscale structures. We present the fabrication of planoconvex microlenses using a hybrid organic-inorganic photo-curable polymer diluted in a gammabutyrolactone (GBL). Microlenses are printed on a glass substrate having different number of drops per lens and different surface conditions. We investigated the influence of the surface conditions on the size and shape of the printed microlenses, which can be affected by wetting properties. Further geometrical and optical characterizations are presented in detail.
