The beam are reflected and scattered and a 3d image is built up from this data. Since then, a range of electron microscope techniques have been developed. Optical parts of a microscope diagram | Copyright: Microbiologynote.com. Parts of Microscope: 1) Eyepiece, 2) Nose piece, 3) Objective lens, 4) Stage clips or Slide holder, 5) Aperture, 6) Stage, 7) Adjustment knobs, 8) Stage controls, 9) Condenser lens, 10) illuminator.

The name derives from the fact that the entire field of view in the microscope is uniformly illuminated, and can be viewed through eyepieces or photographed using a camera. In confocal microscopy, on the other hand, a focused spot of light is scanned across the specimen to record an image. Apr 8, 2020 2) Depth of focus in electron microscopy is very high. 1 point 4) Condenser lens controls the size and intensity of electron beam in TEM.
