The two images acquired in the first step already gave an impression of the field illumination. Homogeneous illumination is particularly important for quantitative analysis, i.e. the comparison of intensities in different regions of the field of view. Therefore the following test provides a more quantitative analysis of the field illumination.

requirements

  • mirror slide
    • alternatively: reflective surface (i.e. glass slide, gold-coated surface)

acquisition

  • 80/20 mirror, laser of interest (1 line of each laser), pinhole 1 AU
  • focus on reflective side of mirror
  • try to obtain "japanese flag"
