Optical equipment refers to devices that utilize light to enhance vision or capture images. Common examples include lenses, microscopes, and telescopes. These tools are essential in various fields, such as medicine, astronomy, and photography, allowing users to observe objects that are too small or too far away to see with the naked eye. The functioning of optical equipment often relies on the principles of refraction and reflection. Lenses bend light to focus images, while mirrors reflect light to direct it. This technology plays a crucial role in scientific research, education, and everyday activities, improving our understanding of the world around us.
