'''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). There are three well-known branches of microscopy: [[optical microscopy]], [[electron microscopy]], and [[scanning probe microscopy]].<br />

== History ==<br />
[[Microscopy]] has been a dynamic field since its inception during the 17th century. The first microscope was invented by [[Zacharias Jansen]] in the 16th century. This was a simple microscope with a magnification of 3x. Later, [[Antonie van Leeuwenhoek]] improved the microscope and was the first to observe and describe microorganisms.<br />

== Types of Microscopy ==<br />
There are several types of microscopy techniques, each suited for specific uses. The most commonly used techniques are:<br />
<br />
* [[Optical microscopy]]: This is the oldest, simplest and most widely used form of microscopy. Objects are illuminated with light, which is collected by a lens and magnified.<br />
<br />

<br />
* [[Electron microscopy]]: This type of microscopy uses a beam of electrons instead of light to create an image. It has a much higher magnification and resolution than light microscopy.<br />

<br />
* [[Scanning probe microscopy]]: This form of microscopy measures the interaction between a probe and a surface to create a detailed 3D image.<br />

== Applications ==<br />
Microscopy is used in many fields, but is particularly important in the field of [[biology]] and [[medicine]]. It is used to study the structure and function of cells ([[cell biology]]), the tissues they compose ([[histology]]), and the organs and structures made up of those tissues ([[anatomy]]). In medicine, microscopy is used to diagnose disease at a cellular level ([[pathology]]).<br />
