After successful completion of the course, students are able to specify optical materials, to calculate basic optical ray paths, to analyse fundamental laws of imaging, to derive aberrations and their corrections, to formulate the influence of aperture stops, to categorise basic types of optical devices as well as to describe STED microscopy. Furthermore they can explain the fields of application of light microscopy, especially taking into account the diffraction-limited resolution limits.

Students can specify optical materials and, based on this, calculate basic optical raypaths by applying the industry-standard sign system.

They analyze the fundamental laws of imaging on basis of planar or curved (also aspherical) surfaces as well as lenses and lens systems.

Furthermore, they are able to derive the aberrations of an optical system and their correction as well as to formulate the influence of the ray bundle limiting by aperture stops.

Based on this basic knowledge, students are able to discuss the basic types of optical devices (magnifying glass, telescope, microscope), in particular they are able to visualize the optics of the microscope on the basis of Abbe's theory (wave-optics / diffraction).

Last but not least, students will be able to describe STED microscopy (Nobel Prize Stefan W. Hell 2014).

The practical part of the course consists in hands-on of the microscopes at the institute or in a visit of the optics laboratory at the HTL Mödling, Department of Mechatronics, respectively, where the students can demonstrate the handling of these devices.

All contents of the course are explained by the script, after each chapter a calculation of exercises is performed.

During the lecture, the lecturer intensively uses the free-of-charge calculating programs LINOS WINLENS and LINOS PreDesigner. Students can download these softwares at www.winlens.de and are thus able to visually understand the contents of the course.

A lecture unit will be dedicated to hands-on on the devices at the TU Vienna; another (voluntarily, in the summer semester) the optics laboratory of HTL Mödling.

There are also smaller optical devices (lenses, magnifying glasses, objectives, eyepieces, binoculars, etc.) from the fundus of the lecturer as illustrative objects "to grasp" brought to the lecture.

Attention: the lecture will take place in academic year 2019/20, will be suspended during academic year 2020/21 and will be continued presumably in academic year 2021/22.

viva voce (oral examination, and a little bit in writing). The questions have to be answered with the aid of sketches / formulae. A list of questions as PDF-file is available via download (check this for details).

Registration by TISS will do.

Lecture notes for this course are available and can be downloaded as PDF-file via "Communication - Documents - Literature".
