The human eye, on the other hand, does not function as a digital camera. In favourable light, two lines separated by at least 0.6 arc minutes (corresponding pixel size: 0.3 arc minutes) can be distinguished. Assume your overall plane of view is a 120-degree horizontal field and a 60-degree verticalRead more
The human eye, on the other hand, does not function as a digital camera. In favourable light, two lines separated by at least 0.6 arc minutes (corresponding pixel size: 0.3 arc minutes) can be distinguished. Assume your overall plane of view is a 120-degree horizontal field and a 60-degree vertical plane. Then your eye’s resolution is: 120 * 120 * 60 * 60 / (0.3 * 0.3) = 576000000 pixels = 576 Megapixels.

Electrons have a wavelength that is substantially shorter than photons (2.5 pm at 200 keV). As a result, an electron microscope's resolution for photographing cellular structure or proteins is theoretically limitless. The resolution of electron microscopes is practically restricted to 0.1 nm due toRead more
Electrons have a wavelength that is substantially shorter than photons (2.5 pm at 200 keV). As a result, an electron microscope’s resolution for photographing cellular structure or proteins is theoretically limitless. The resolution of electron microscopes is practically restricted to 0.1 nm due to the objective lens arrangement.
