Intended learning outcomes

After completing the course the student should be able to:

  • adjust the illumination system to obtain optimal performance in transmission microscopy.
  • select a suitable light source and optical filters, and correctly adjust the illumination system for fluorescence microscopy.
  • select a suitable objective (correction, immersion etc) for various types of microscopic investigations.
  • select a suitable contrast method (phase contrast, DIC, fluorescence, darkfield etc) and correctly use this technique to obtain high-quality images.
  • calculate the expected image quality regarding resolution and signal-to-noise ratio for different practical imaging situations.
  • understand and be able to describe the physical limitations for microscope performance concerning resolution and signal-to-noise ratio.
  • describe performance for different types of microscopes by using (and in some simple cases calculating) optical transfer functions.
  • select a suitable sampling density for digital image recording in microscopy.
  • do computer processing of microscopic images to visualise three-dimensional structures.
  • perform quantitative measurements in microscopic images using a computer.
