Increasing Shape Accuracy in The Laser-based - Aachen, Deutschland - Laser Technology
Beschreibung
The conventional production of optics is very time-consuming and costly in terms of shaping and polishing. The urge for inexpensive, individualized components therefore requires new manufacturing technologies.One such approach is the use of laser radiation to ablate the glass layer by layer and then polish it by remelting.
The two sub-processes are carried out with ultra-short pulsed or continuous CO2 laser radiation and are each based on the characteristic interaction with transparent materials.
The development of the individual processes is already well advanced, but there is a lack of knowledge about combining the processes into a production chain.
What you will do
- Investigation of the combination of laser ablation and laser polishing for the production of complex precision optics, e.g. aspheres and freeforms
- 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
- Practiceoriented thesis in an innovative working environment
- A creative, diverse, multidisciplinary team with indepth knowledge
- Tasks with responsibility and creative freedom
- Close cooperation between science and industry
- Firstclass equipment in the laboratories and offices
- Good transport links (bus connections, free parking garage)
- Flexible working hours for a better workstudy balance
