The numeric aperture determines resolution,which is the ability to distinguish two objects close to one another as distinct entities.Increasing the numeric aperture increases resolution.Lowering the condenser changes the amount of light coming through the specimen.Magnification,whether from the ocular or objective lens,or the two combined,simply makes an image larger but cannot improve resolution.Adjusting the focus controls merely makes an image sharper,but this does not increase the resolution.
