Prism for Elipsometry
Microoptics is one of the applications for 3D laser lithography. This illustration shows a fabricated micro prism with a grating on one side.
Since only one optical surface is needed, dynamic slicing and hatching can be used to increase throughput. Multiphoton polymerization is a flexibles technique that allows different quality and various functionality surfaces to be maintained on the same structures depending on the needs of the application. These microoptical components can be printed on functional devices such as fiber tips to filter and detect light signals.
Multiphoton-polymerization (MPP) is a technology that enables the production of arbitrary shape polymeric structures within submicrometric resolution. First, a photoresist sample is prepared by drop-casting polymer material mixed with a photoinitiator on the glass slide and then pre-baking.
A feasibility study is composed of several steps, including researching methods for fabricating micro-structures, fabricating a micro-structure prototype, measuring and aligning the prototype with technical requirements, and finally preparing a study report.
