Microscopy is utilized in research and healthcare facilities to visually analyze samples at the cellular level. Microscopes are a critical piece of laboratory equipment that allow workers to view samples for anomalies that can be used to identify microorganisms (such as bacteria) that would be impossible to see with the naked eye. Lenses, eyepieces, and covers attach to microscopes to bring samples into focus. Arms and stands hold eyepieces and provide a stage to hold slides or samples. Microscope cameras connect to the eyepiece to capture images.
