Second Condenser Lens Tem at Veronica Reyes blog

Second Condenser Lens Tem. A typical tem uses a system of two condenser lenses to control the beam incident on the sample. In tem systems, the first condenser and final projector lenses have short focal length and their designs are similar to that of the objective lens. Condenser lenses this lens is used to form the beam and limit the amount of current in the beam and it is also used to control the diameter of the. Used to form diffraction (and phase) contrast images and. Used to change convergence angle and electron beam coherence. The first lens demagnetises the source, either. The second condenser (c2) lens is a weak magnetic lens (f ≈ several cm) that provides little or no magnification (m ≈ 1) but allows the. In tem, the second condenser lens lens is used to defocus the beam on the specimen so in this way the size of the area which the beam hits can be. The lenses after the electron source in tem are a condenser lens, an objective lens, an intermediate lens, and a projector lens.
