The light microscope helps see the microscopic world that the naked eye cannot see. If there were no microscopes in the world, than it would be very difficult to understand the many particles that surround the living world. The purpose of this lab experiment is to become familiar with a microscope. It is hypothesized that it will be difficult to use the microscope without any previous training and that the parts and their function must be learned in order to use it correctly. To test the hypothesis, a short lab experiment will be conducted using slides that have a small piece of paper with the letter e typed on it. During this experiment, the low and high objectives will be used in order to observe the material on the slide. Materials and Methods:
A binocular compound microscope, brand name Olympus with a blue filter was used for the purpose of this lab. “The compound microscope[->0] is a very common type of microscope. The term "compound" means more than one lens is used. In the compound microscope you have two lenses. The primary lens is the one closest to the object and then there is the secondary lens, which is furthest from the object. The secondary lens is used to magnify the image of the primary lens. The primary lens is aimed at the condenser, or stage, and this is where the object to be magnified in the form of a slide is placed. A modern compound lens can magnify the original diameter of specimens 1000x to 2000x. The stage is illuminated with a light that shines through a diaphragm. The diaphragm is used to control the amount of light. This microscope is very common today and is still used as a teaching[->1] microscope.” Different Types of Microscopes & How Each One Functions | eHow.com[->2] http://www.ehow.com/list_6374011_different-types-microscopes-one-functions.html#ixzz27u6ecxtJ...
