Program 24 – 25 October

Course OPTOMECHANICS by Daniel Vukobratovich

Unique opportunity to meet one of the most famous opto-mechanical professors: Mr Daniel Vukobratovich,  Senior Scientist at Ratheyon as well as professor at Tucson University.

Opto-mechanics will cover subjects on optics and optics mounting alignment, dynamics and thermal stability or material stability. A wide variety of examples from space, astronomy, defense and industry will be used to clarify t heory. Many practical analytical  tools will be presented The course will be presented by mr Daniel Vukobratovich Senior Scientist at Ratheyon as well as professor at Tucson Unive rsity. He has been involved in a large number of publications and has an impressive track record on opto-mechanical developments.

The courses are meant for engineers and systems engineers, PhD students or involved Technicians to learn about optics or opto-mechanics. The important basics as well as details on state of the art developments will be presented. Hands on design exercises using state of art tools are part of the program.
