Microscope Definition
Posted on by admin
Microscope an instrument for magnifying the size of an object. The simple microscope is the hand lens, but the instrument commonly used is the compound microscope which consists of two sets of lenses: eyepiece and objective. The compound microscope can magnify 600 - 1000×using an oil interface between lens and slide (see OIL-IMMERSION OBJECTIVE LENS), and with suitable eyepieces objects. You can adjust the contrast on most microscopes just like you adjust the focus. Contrast refers to the darkness of the background relative to the specimen. Lighter specimens are easier to see on darker backgrounds. In order to see colorless or transparent specimens, you need a special type of microscope called a phase.

The coarse focus on a microscope is provided to move theinstrument quickly to where it is nearly in focus. Some microscopesonly have a coarse focus. The fine focus is used to move withslower and more precise adjustment to where the instrument isexactly in focus.
