[0] Transmission Electron Microscope (TEM) [1] TEM is electron illuminated. This gives a 2-D view. Thin slices of specimen are obtained. The electron beams pass through this. It has high magnification and high resolution. [2] more than $50,000 [4] vacuum [5] Thin films of collodion or other supporting material on copper grids [6] one electrostatic lens and a few electromagnetic lenses [7] Electrical i.e. current of the objective lens coil is changed. [8] Electrical i.e. changing current of the projector lens coil [9] Electron scattering [11] plant cell [3]
