What are different ways for scientist to use a hand lens?

Scientists use hand lenses to closely examine small details in specimens, such as identifying plant and insect features, assessing mineral textures, or studying biological samples. They can also use hand lenses to enhance observations in fieldwork, helping to distinguish between similar species or detect subtle patterns that are not visible to the naked eye. Additionally, hand lenses are valuable in quality control processes, allowing scientists to inspect materials and products for defects or irregularities.
