Dear all,

On EM-learning.com there is a full section on the condenser system and parallel illumination where it is demonstrated on a two-condenser system (this is the same for any tecnai (F20/F30/Polara) or Talos (Arctica/Glacios)) how to set parallel illumination in both nP and uP, each beam size for each aperture and the consequences of going off parallel. You could also order a smaller 20 mu aperture to make a smaller beam in uP if you prefer to work in that mode.
