Which of the following component of TEM focuses the beam of electrons

1.	Which of the following component of TEM focuses the beam of electrons on the sample?(a) ocular lens(b) condenser lens(c) stage(d) columnThe question was asked in final exam.My question comes from Techniques in section Techniques in Cell Biology of Cell Biology
Answer» Right option is (b) CONDENSER lens Easiest explanation: The condenser lens focuses the electron beam on to the SPECIMEN, in case of transmission electron microscope. The specimen is supported on the GRID holder and placed INSIDE the COLUMN.
