    we had been able to learn the proper technique of using the optical microscope and preparation of different types of slides. Optical microscope, often referred to as light microscope, is a type of microscope which uses visible light and a system of lenses (4X, 10X, 40X and 100X) to magnify images of small samples. Image from an optical microscope can be captured by normal light-sensitive cameras to generate a micrograph. Microscope is one of the best technology provide information such as the staining

    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

    Electron Microscope The electron microscope has become one of the most widely utilized instruments for materials characterization. An electron microscope is a scientific instrument that allows us to “see” objects so small that they cannot be seen in any other way. (CITE) Electron microscopes have allowed scientists to see individual molecules and atoms for the first time. Most microscopes, including those in schools and laboratories today, are optical microscopes. They use glass lenses to enlarge

    completing this lab was to observe how microscopes function. The invention & evolution of the microscope has been an ongoing process since the Middle Ages, when the first convex magnifying lenses were introduced. In 1590, the Jansen Brothers invented the first compound microscope (two or more lenses).However, Antony van Leevenwenhoek created the first “true” microscope, in 1665, with 300x magnification & unbelievable resolution. During the late 1700’s, the microscope was reinvented with 1500x magnification

    instruments is the scanning electron microscope (SEM). This instrument can be used in examining physical evidence found at crime scenes. There have been a number of scientists that have developed and improved the SEM. SEM is very significant in forensics because it can narrow down size, shape, and chemical composition. The scanning electron microscope is always growing and becoming a great impact on forensic science. We will start of learning where the scanning electron microscope (SEM) began. Knoll built the

    crime laboratories depended merely on the microscope to study the structure and composition of matter. In the early 1950s, the scanning electron microscope (SEM) was developed and it added a new element to forensic science, which was previously unattainable within the restrictions of the ordinary light microscope. All other traditional microscopes use light coming off the specimen to produce a magnified image (Saferstein, 2011). The SEM is a special microscope in the sense that it uses electrons instead
