**4. Usage areas of scanning**

Scanning Electron Microscope, besides its use in research and development studies in many branches, is widely used in microelectronics chip production, error analysis in different branches of industry, biological sciences, medicine and criminal applications. Among them,

In Forensic Medicine: It is used to compare materials such as metal parts, wood chips, paint and ink, and also to examine evidence in police laboratories by examining materials such as hair, skin pieces, thread. It is also used effectively in the fields of medicine such as Anatomy, Biochemistry, Physiology, Microbiology, Pathology, Toxicology. It is also used in fields such as dentistry, Biological Botany and Cell Biology in the field of health [5].

In metallurgy: Metals are used to determine the durability of metals in different conditions such as hot and cold [6]. Also in this field; SEM analyzes are also used in many fields such as Material Sciences (Content Analysis of Materials), Materials Research, Investigation of Rough Surfaces, Surface Topography, Investigation of Material Damages, Magnetic and Superconducting Materials, Geological Sections, Soft Materials and Crystallization/Phase Transformation.

It is used to determine the durability of metals used in aircraft, automotive, defense industry, vehicles such as aircraft, automobiles, trains, ships, which require the use of strong metal for security reasons.

In Scientific Research: Biologists study plant and animal tissues, chemists use microscopic crystals, metal, plastic, ceramics, etc. They make use of SEM in the analysis.

In addition, it is of great importance to make use of the EDX features of SEM devices for additional analysis such as sample content determination and a color mapping of this content.
