Importance Of Light Microscope

Light Microscopes

Introduction

Nobody in the entire world is capable of seeing microscopic things with a naked eye. For years, this has been a huge problem against humanity; people have died of diseases that scientists could not deal with or know about because they lacked of having the correct technology. Back then in the 1400s, they were not aware of bacteria, as microscopes were not invented during those days. They could only see the effect that the bacteria created, but still could not find out the reason for the illness.

Since Zacharias Janssen created the first compound microscope in the late 1500s, students, scientists, researchers and law enforcement agencies, have used this tool to see and experiment minuscule objects. During the years, the microscope has been modified and other types of microscopes have been created, such as the electron microscope to do other specific functions. Nowadays, one of the things the microscope is most used for is to do advanced research to support medicine and to help prevent illnesses.

What is a Light Microscope?

The light microscope, also called compound microscope is a machine that enables you to see tiny objects and creatures in a more extended size (things can be magnified more than 1000%). Its function is similar to a refracting telescope, except that in a microscope, the object is very close to the objective lens. In comparison to a telescope, a microscope must gather light from a tiny area of a thin, well-illuminated specimen that is close-by. Therefore, the microscope does not need a large objective lens. Instead, the objective lens of a microscope is just small and spherical, which means that it has a much shorter focal length on either side. It brings the image of the o...
