confocal microscopy is a technique used in scientific research that allows for the visualization of objects at very high resolution. It works by using a laser to focus on a specific plane of the sample, while blocking out any unwanted light from other planes. This allows for a clearer and more detailed image of the sample, making it useful for studying biological samples, materials science, and other fields of research. Confocal microscopy has become a valuable tool in research due to its ability to provide detailed images of samples in three dimensions.
