Professional microscopist here (I think that's the first time I've got to say that in real life). EJN hit the nail on the head - microscope resolution is dictated by the numerical aperture of your objective lens and the wavelength of light you're using for imaging, so the additional m...
Simple lenses, like a magnifying glass or a Coddington lens, use a single lens to magnify the image in front of it, while compound lenses, such as a jeweler's loupe or a microscope, use two or more lenses to increase the magnification of an object. The total magnification of a compound...
As you can see, the formula still remains a vague description and does not consider the resolution. This means that scaling the same image to a bigger screen will cause the magnification number to change. What is the field of view of a microscope?

After simple conversion, this formula is approximately equal to 1/2 λ, which means that one-half of the wavelength is actually the resolution limit of an optical microscope. Later generations defined it as the "Abbe limit". The shortest wavelength in visible light -- violet light, is about...

Regardless of whether you are an academic researcher or industrial laboratory specialist, all scanning electron microscope (SEM) operators are confronted by their scale bar at some point. The burning question is usually something like, “How do I know this scale bar is accurate?” Mak breaks down...
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnification observation apparatus such as a digital microscope and a microscope that images and displays a magnified image, and a method for photographing a magnified image. 2. Description of the Related Art...
Traditional microscopy provides only for a small set of magnifications using a finite set of microscope objectives. Here, a novel architecture is proposed for quantitative phase microscopy that requires only a simple adaptation of the traditional off-axis digital holographic microscope. The architecture ...
