Fundamental Optical Design (6 ECTS), Helsinki region

Course description
The aim of the course is to teach the fundamentals of optical design, especially to provide theoretical foundations of geometrical optics combined with basic design examples. After this course you will have the required theoretical and practical skills to start optical design.  

Language

Written material is in English, speaking language depending on the participants, either English or Finnish.

Participants have to have own computers during the course. During the course participants should have at least a spreadsheet program available. As teaching software the optical design and optimization program WinLens3D will be used. The price of the full version is approximately 500 €. The participants can download a free version called WinLens3D Basic, which has all the functions of the full version except for the optimization module. Download free version.

Any other optical design program possibly available can be used.
 

Content description
Note that detailed plan may change depending on participant’s wishes

  1. Fundamentals of geometrical optics, plane waves, refraction and reflection, limits of ray optics
  • The behavior of an electromagnetic wave at the boundary of media is the foundation of geometrical optics.
  • Optical applications depend on the refraction and reflection of waves.
  • The polarization of the wave affects its behavior at boundaries.
  • Applications are based on both the ray properties and the wave properties of the electromagnetic wave. The conditions for those and the limits of them are examined.
