A projection microscope is an advanced optical device that magnifies small specimens and projects their images onto a screen for easy viewing. It is commonly used in classrooms, laboratories, and research facilities to allow multiple people to observe specimens simultaneously. Unlike traditional microscopes that require direct eyepiece viewing, this microscope uses a strong light source and lenses to project clear, enlarged images. It is useful for studying biological samples, intricate structures, and micro-organisms in educational and professional settings. Projection microscopes enhance learning and analysis by providing a detailed and collective viewing experience.
