True or False: Increased numerical aperture results in more light entering the lens and increases image detail.

With an increased numerical aperture (NA), more light is able to enter the lens of a microscope, which enhances the brightness and detail of the observed image. This is particularly important in microscopy because the clarity and resolution of the image are influenced by the amount of light gathering ability of the lens system. A higher NA allows for improved resolution, making it possible to distinguish finer details in the specimen being examined.

The concept of numerical aperture is integral in determining how well a microscope can resolve small structures within a specimen. As the NA increases, the ability to collect light and resolve fine details also increases, leading to high-quality images that reveal more information about the sample’s morphology and structure. Thus, the statement that increased numerical aperture results in more light entering the lens and increases image detail is accurate.
