Optical microscopy is a technique used in scientific research and various fields of study to magnify and view objects that are not visible to the naked eye. It uses visible light and lenses to create a magnified image of the sample being examined. Optical microscopy can be used in various applications including biology, materials science, forensic science, and nanotechnology. It provides high resolution images of samples and allows researchers to study the structure and properties of materials at the microscopic level. Optical microscopy is a valuable tool in scientific research for studying the morphology, composition, and behavior of biological and non-biological samples.
