microscopic entities not seen by the unaided eye[1]. Today there are many types, but here the focus will be on digital microscopes[2]with electronic image sensors, but no eyepieces, and stereo microscopes[3,4]with eyepieces. Additionally, a stereo microscope can be equipped with a digital ...

The invention describes a new device (1) for changing the automatic lens (109) imaging a microscope planar laser beam depending on the magnification desired at all times. The device (1) comprises: at least two supports (2) configured for... JR Lorenzo,A Miguel,CN Arrieta 被引量: 0发表...
Microscope - Image Formation, Optics, Magnification: The objective collects a fan of rays from each object point and images the ray bundle at the front focal plane of the eyepiece. The conventional rules of ray tracing apply to the image formation. In th
Electron microscope magnification Magnification is a very simple concept, but it sometimes can create confusion because of its own definition. The aim of this blog is to clarify magnification inscanning electron microscopes(SEM) and focus on other parameters which can describe b...
The compound microscope The limitations on resolution (and therefore magnifying power) imposed by the constraints of a simple microscope can be overcome by the use of a compound microscope, in which the image is relayed by two lens arrays. One of them, the objective, has a short focal length...
