Optical MicroscopesIntroductionNo one in the world is able to see microscopic things with the naked eye. For years this has been a huge problem against humanity; people died of diseases that scientists couldn't address or know about because they didn't have the right technology. Back then in the 1400s they didn't know about bacteria, because microscopes hadn't been invented back then. They could only see the effect created by the bacteria, but they still could not discover the reason for the disease. Since Zacharias Janssen created the first compound microscope in the late 1500s, students, scientists, researchers and law enforcement have used this instrument to see and experiment with tiny objects. Over the years the microscope has been modified and other types of microscopes have been created, such as the electron microscope to perform other specific functions. Nowadays, one of the things the microscope is most used for is doing advanced research to support medicine and help prevent disease. What is an optical microscope? The optical microscope, also called a compound microscope, is a machine that allows you to see tiny objects and creatures of larger dimensions (things can be magnified more than 1000%). Its function is similar to that of a refractor telescope, except that in a microscope the object is very close to the objective lens. Unlike a telescope, a microscope must collect light from a small area of ​​a thin, well-lit specimen that is nearby. Therefore, the microscope does not require a large objective. Instead, a microscope's objective lens is simply small and spherical, meaning it has a much shorter focal length on either side. It bears the image of the half... half of the card... have had a great impact on human society. Eventually people learned that there were microscopic organisms and particles that couldn't be seen but had the potential to make them sick, and cleanliness improved dramatically.
