Microscope Lab Report

The purpose of this experiment without laboratory work is to observe the function of the microscope. Since the Middle Ages, the invention and development of the microscope was a continuous process when the first convex lens was introduced. In 1590, Jansen Brothers invented the first compound microscope (two or more lenses). However, Antony van Leevenwenhoek produced the first "real" microscope with a magnification of 300 times and a remarkable resolution in 1665. In the late 1700's, the microscope was reinvented at 1500 times magnification.

"Unfortunately, the early Jansen microscope has not survived until now, it appeared in Middelburg, the Netherlands in the 17th century and was reported as being the earliest microscope of Jansen.The microscope is currently in the Middelburg Museum.The historian It has doubts about the origin of the above microscope, which is very similar to at least the Janssen microscope, as it is consistent with the known explanation of the Royal Janssen microscope.In accordance with the custom of the time, Jansens was a member of the royal family , They knew that they would send the microscope to Orange Prince Morris and Austria to one of Alberta's Grand Dukes.

A microscope is a device used to study small objects that are invisible to the naked eye. There are three types of microscope: optical microscope, electron microscope and scanning probe microscope. (1) The six types of microscopes discussed in this report are reflected and transmitted by an optical microscope, a scanning electron microscope (SEM), a transmission electron microscope (TEM), a focused ion beam (FIB) and an atomic force microscope (AFM) did. Reflective optical microscope is a microscope that uses a visible light and lens system to magnify a small sample image. It is used for the inspection of opaque samples and other materials such as opaque ceramics. The reflected light passes through the objective lens, and the objective lens functions both as a condenser and as an objective lens and collides with the sample. Next, reflect the objective lens, the head, the eyepiece, and finally to the eyes and return the specimen to its original position. (2)

The microscope used was a compound optical microscope. It is usually dual purpose (two eyepieces). The compound optical microscope combines the power and light of the lens to enlarge the body being observed. Eyepieces allow for 10 or 15 times magnification and can be rotated into the field of view when combined with 3 or 4 objective lenses, typically producing higher magnifications up to about 1000 times maximum. Materials laboratory observes and captures images of size welding nugget and heat affected zone (HAZ) using microscope
