In cooperation with the Chair of Laser Technology LLT at RWTH Aachen University, the Fraunhofer Institute for Laser Technology ILT, a leading center for contract research and development in the field of laser technology, is offering the opportunity to write a thesis in the field of "Polishing" on the subject of "Increasing shape fidelity in laser-based production of individualized microlens arrays".
Involume structuring of quartz glass using ultrashort pulsed laser radiation and subsequent etching (selective laser-induced etching, SLE) can be used to produce microstructures that cannot be produced economically using conventional methods, e.g. individualized microlens arrays for laser applications. In order to achieve an optical surface quality, polishing by remelting is then applied using continuous CO2 laser radiation. The development of the individual processes is already well advanced, but there is a lack of knowledge on how to combine the processes into a production chain with sufficient dimensional accuracy.
What you will do
* Investigation of SLE and laser polishing for the production of individualized microlens arrays
* Consideration of the interaction of the processes on shape fidelity and surface quality
* Production of a process strategy for demonstrator optics with defined target geometry and optical surface quality
What you bring to the table
* You are studying physics, mechanical engineering, materials science or a comparable course of study
* You are motivated and are characterized by an independent and conscientious way of working
* Knowledge of laser technology is an advantage, but not essential
What you can expect
* Practice-oriented thesis in an innovative working environment
* A creative, diverse, multidisciplinary team with in-depth knowledge
* Tasks with responsibility and creative freedom
* Close cooperation between science and industry
* First-class equipment in the laboratories and offices
* Good transport links (bus connections, free parking garage)
* Flexible working hours for a better work-study balance
The position is temporary until completion of the thesis.
