● Minify the aperture below 60% of the objective’s numerical aperture unless in a special case, for instance, observing an almost transparent specimen. ● The numerical aperture is marked on the objective. For example, the mark “ 10/0.25 ” means the magnification is 10×, and the numerical aperture is 0.25.
