A hemocytometer. The two semi-reflective rectangles are the counting chambers. The hemocytometer (or haemocytometer, or Burker's chamber) is a counting-chamber device originally designed and usually used for counting blood cells. [1] The hemocytometer was invented by Louis-Charles Malassez and consists of a thick glass microscope slide with a ...
Digital microscope. An insect observed with a digital microscope. Entomologist using a digital microscope to magnify a miniature insect. A digital microscope is a variation of a traditional optical microscope that uses optics and a digital camera to output an image to a monitor, sometimes by means of software running on a computer.
To enable several people to use them at once, each microscope is able to project images with a built-in projector. [6] The Foldscope is designed to be assembled by the end user, and hence is color-coded to help with the assembly. [5] Each unit costs less than one US dollar to build, with estimates varying from 50 cents to 97 cents. [5] [6]
003665. [edit on Wikidata] A blood smear, peripheral blood smear or blood film is a thin layer of blood smeared on a glass microscope slide and then stained in such a way as to allow the various blood cells to be examined microscopically. Blood smears are examined in the investigation of hematological (blood) disorders and are routinely ...
Microscopy. Scanning electron microscope image of pollen (false colors) Microscopic examination in a biochemical laboratory. Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye).

In 1964, Adam S. G. Curtis coined the term Interference Reflection Microscopy (IRM), using it in the field of cell biology to study embryonic chick heart fibroblasts. [1][2] He used IRM to look at adhesion sites and distances of fibroblasts, noting that contact with the glass was mostly limited to the cell periphery and the pseudopodia. [1]
A travelling microscope is an instrument for measuring length with a resolution typically in the order of 0.01mm. The precision is such that better-quality instruments have measuring scales made from Invar to avoid misreadings due to thermal effects. The instrument comprises a microscope mounted on two rails fixed to, or part of a very rigid bed.
Transport by gravity using an upright microscope (called GAM, gravity-assisted microdissection) or transport by laser pressure catapult; the most recent generation utilizes a technology based on laser induced forward transfer (LIFT). With cut-and-capture, a cap coated with an adhesive is positioned directly on the thinly cut (5-8 μm) tissue ...
