👉 The term "ultramicroscope" refers to a type of microscopes that are designed for extremely small objects, typically less than 100 micrometers (μm) in size. These microscopes use advanced technologies such as confocal microscopy and electron microscopy to magnify the images of these tiny objects, allowing scientists to study them up close and from different angles. Ultramicroscope technology has revolutionized research in various fields, including medicine, biology, chemistry, and materials
