Fixed power microscopes, also known as monocular microscopes or low-power microscopes, are microscopes that have a single, fixed magnification. They are called "low-power" because they typically have a magnification of 10x or less. Fixed power microscopes are simple and inexpensive instruments that are often used in educational settings, such as schools and colleges, to introduce students to microscopy. They are also used in a variety of other settings, including industrial and research laboratories, to perform routine tasks that do not require high magnification. Fixed power microscopes are typically very easy to use, as they do not have any moving parts or adjustable objective lenses. The user simply places the specimen on the stage and looks through the eyepiece to view the image. Because they have a fixed magnification, fixed power microscopes are not able to produce images at different magnifications. Instead, they are used to observe relatively large specimens, such as insects, plant cells, and other biological specimens, at a low magnification.
