he invented the microscope
Galileo contributed to the field of microscopy by improving the design of the compound microscope, which allowed for greater magnification. He also made important observations using the microscope, such as discovering the moons of Jupiter.
Galileo heard of their experiments and stared experimenting on his own.
Dark field microscopy (dark ground microscopy) describes microscopy methods, in both light and electron microscopy, which exclude the unscattered beam from the image. As a result, the field around the specimen (i.e. where there is no specimen to scatter the beam) is generally dark.
FESEM stands for Field Emission Scanning Electron Microscopy. It is a high-resolution imaging technique in electron microscopy that uses a field emission electron source to produce a fine electron beam for imaging the surface of a specimen at nanoscale resolution.

The purpose of bright field microscopy is to provide a simple, yet effective, technique for use in observing microscopic properties of samples.

Galileo did not invent the microscope, but he made significant improvements to its design in the early 17th century. He created a compound microscope that combined multiple lenses, which enhanced magnification and clarity. His innovations contributed to the development of microscopy, allowing for more detailed observation of small objects and laying the groundwork for future advancements in the field.
Dark field microscopy improves contrast by illuminating the specimen with oblique light, helping to visualize transparent or unstained samples that would otherwise be difficult to see under bright field microscopy where the specimen appears transparent against a bright background. Dark field microscopy enhances visualization of small particles, living organisms, and thin specimens due to the increased contrast and detail provided by the technique.
