Write a summary of what you have learned in "Introducing the Microscope". Be sure to include steps on how to focus, how to solve for magnification, and what a field of view is and how to measure it.

"Introducing the Microscope" is a text that shows what a miscroscope is, how it works, its composition and its functions. This is a very important text for those who have no experience with this equipment, but can use it at any time.

One of the most important points in the text is about the operation and correct use of the microscope. Where concepts are explained, promoting the proper functioning of the equipment.

According to the text, we must have a full conviction of the microscope's field of view, which is the vision we have when we position our eyes under the microscope to visualize tiny and invisible elements with the naked eye.

However, the field of view needs to be focused and this is done with the manipulation of the microscope that will allow the vision to have a very well developed and detailed quality.

In addition, a microscope has many lenses, which can increase and decrease the size of the image. This promotes the enlargement of the image and makes the image can be seen more closely and in more detail.
