The History of the Microscope

The first microscope was created hundreds of years ago. In the passing centuries, microscopes evolved into powerful, strict tools that allow scientists to view tiny objects at a level of information that seems unreal. There are a wide array of ready microscopes, from the aggregate microscopes commonly found in high school science classrooms to noteworthy scanning tunneling and electron microscopes used by Nobel Prize winners.

Most historians agree that two Dutchman made the first microscope in 1590. Zaccharias Janssen and his son Hans were two eyeglass makers who experimented with putting manifold lenses together in a tube. They found that objects under the tube were greatly enlarged. Over the next hundred years, scientists Robert Hooke, Anton van Leeuwenhoek, and others further refined the work of the Janssens and used microscopes to study insects, blood, and other items. Scientists have prolonged microscopes into the present day. Now, microscopes can show tiny particles that are unseen by the naked eye in very exact detail.

Microscope

Microscopes control on several principles. Most tasteless microscopes have two different lenses. Viewers look through the ocular lens, also known as the eyepiece. There is an additional one lens, called the objective lens at the end of the ocular lens. The objective lens is a sphere shaped lens settled above the stage of the microscope. population place the object they want to study on the stage and can adjust the lenses to bring the object into focus. Most microscopes have an adjustment knob for tasteless focus and one for fine focus. Many microscopes have several objective lenses with different strengths for users to choose from. The lenses are arranged on a circular platform that can be rotated to have the different lenses put into place under the ocular lens. Microscopes also need a light source of some kind underneath the stage. Most industrial microscopes have a light bulb, but many high-end microscopes use lasers or electrons for illumination.

Microscopes have been used to make countless vital scientific discoveries. They are invaluable tools used in a collection of scientific fields that enable researchers to make discoveries that would be impossible with the naked eye.
