What Is a Biological Microscope?

There are several types of biological microscopes.

Biological microscopes are microscopes used for viewing biological fluids under high magnification. They are used in high schools, universities and professional scientific laboratories. Biological microscopes come in a variety of types and prices.

Types

There are two main types of biological microscopes. They differ based on magnification. A low-power, or dissection, microscope is used for looking closely at larger things like removed organs or dissected insects. A high-power, compound-light microscope has a higher magnification and is used to see bacteria, parasites and other small organisms on a glass slide.

Features

Magnification on a biological microscope is the primary factor in cost and use. Whether high powered or low powered, scientists can choose between zoom optics or fixed magnification optics. Zoom optics gives continuous magnification across a wide zoom range while fixed optics have four to five set magnifications on a rotating turret.

Identification

Although microscopes may differ slightly, there are common features of all microscopes. Starting with a sturdy base, there are two knobs for adjusting the focus: a fine-adjustment knob and a course-adjustment knob. Near the larger knob is the stage where the scientist places the specimen under stage clips. The arm of the microscope connects to the magnification device and a body tube angles upwards to the eye piece for viewing.
