This view is in black and white, yet gives an amazing picture of, for example, the minute hills and valleys of a dinosaur bone. A confocal microscope is a step down from the previous types. It uses a laser beam to illuminate a specimen, the image of which is then digitally enhanced ...
An AFM microscope that small would be nearly invisible wouldn’t it? If you’re touching the tip of an atom or a nanoparticle, then I would assume that the tip would have to be just as small. I can’t imagine a tip that is thinner than a wave of light. I think that were it ...

Although less common now, some pocket models display an image that is reversed. This is due to the microscope using mirrors and lenses to magnify the image, not unlike what happens in your eye. However, a small microscope may not have enough space to hold the mirrors that correctly repositio...
Scanning Objective Lens (4x) A scanning objective lens provides the lowest magnification power of all objective lenses. 4x is a common magnification for scanning
Microscopy is the science of investigating small objects and structures using a microscope. Telescope A telescope is an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, or various devices used to observe distant objects by their emission, ...
Cutaway view of a microscope objective, focusing rays at points under a cover glass. Light on axis comes to a tight focus for rays traced through the microscope objective The diffraction limited spot size is denoted by the circle in the drawing. The points show intersections of rays traced ...
An EM is a microscope that focuses beams of energetic electrons to examine objects up to nano-scales. They utilize the same principles behind an optical microscope, but rather than photons or particles of light, concentrate electrons, charged particles located on the outside of atoms, onto an ...
The fast technological advances of molecular tools have enabled us to uncover a new dimension hidden within parasites and their hosts: their microbiomes. Increasingly, parasitologists characterise host microbiome changes in the face of parasitic infections, revealing the potential of these microscopic fa...
