Source sentences:
text: An image is formed from the interaction of the electrons with the sample as the beam is transmitted through the specimen.
text: When using a field emission source and a specimen of uniform thickness, the images are formed due to differences in phase of electron waves, which is caused by specimen interaction.
text: It is very similar to the phase-contrast microscope whereby the images are formed from the variations in the light either deviated and or undeviated.
text: By scanning the spot or the sample in a raster pattern a complete image can be formed.
text: An image is formed by scanning the pinhole in a raster
text: Changes to the electron beam inside the specimen are recorded and an image is formed based upon these changes.
text: It is termed a scanning electron microscope because the image is formed by scanning a focused electron beam onto the surface of the specimen in a raster pattern.
text: Transmission Electron Microscopy (TEM) refers to a technique where the image (of specimen) is formed by directing a high energy electron beam at a thin sample
text: As the electrons of the beam interact with the sample, an image is formed.
text: Similar to the limitations of TEMs, SEMs yield only greyscale images and it is not possible to observe living specimens as the entire system must be in a vacuum in order for the image to be formed.
