Compound microscopes first appeared in Europe around 1620. [2] [3] The actual inventor of the compound microscope is unknown although many claims have been made over the years. These include a dubious claim that Dutch spectacle-maker Zacharias Janssen invented the compound microscope and the telescope as early as 1590.
The single lens with its attachments, or the system of lenses and imaging equipment, along with the appropriate lighting equipment, sample stage, and support, makes up the basic light microscope. The most recent development is the digital microscope, which uses a CCD camera to focus on the exhibit of interest. The image is shown on a computer ...

There's a problem in cell biology research: to study what happens inside a cell, it has to be destroyed. When scientists use a traditional microscope to observe a cell, they use stains ...
The Virtual Microscope project is an initiative [when?] to make micromorphology and behavior of some small organisms available online. [1] Images are from Antarctica and the Baltic Sea are available at no cost. Images are offered in higher magnification or lower resolution.
The autofocus and phase shift imaging capabilities of digital holographic microscopy makes it possible to effortlessly create label-free and quantifiable time-lapse video clips of unstained cells for cell migration studies. [30] In Figure 5 a label-free time-lapse of dividing and migrating cells is shown. Tomography studies. [31]
In animals, the plasma membrane is the outer boundary of the cell, while in plants and prokaryotes it is usually covered by a cell wall. This membrane serves to separate and protect a cell from its surrounding environment and is made mostly from a double layer of phospholipids , which are amphiphilic (partly hydrophobic and partly hydrophilic ).
The stereo microscope should not be confused with a compound microscope equipped with double eyepieces and a binoviewer. In such microscopes, both eyes see the same image, with the two eyepieces serving to provide greater viewing comfort. However, the image in those microscopes is no different from that obtained with a single monocular eyepiece.
