In general, the objective working distance decreases as the magnification and numerical aperture both increase. The parfocal length is the distance between the specimen plane and the shoulder of the flange by which the objective lens is supported on the revolving nosepiece

Each of these two methods has its limitation. The SELFOC lens' numerical aperture (NA) is low, which limits its light-collection efficiency. A 1:1 lenslet array can have a high NA, but its resolution along the scanning direction is low, which means it is not suitable for 2-D scanning. In this paper, line scan optics with a high NA will be

The SELFOC lens' numerical aperture (NA) is low, which limits its light-collection efficiency. A 1:1 lenslet array can have a high NA, but its resolution along the scanning direction is low, which means it is not suitable for 2-D scanning What you are probably speaking of here is the "numerical aperture", an indicator of the microscope lens property that is rather equivalent to the "exposure impact" of a camera lens. A certain numerical aperture of a microscope objective generally corresponds to a certain f/number, although there are some complications. However, the numerical aperture (an indication of resolving power of an objective) of a 100x dry objective is much lower than that of a 100x oil immersion objective and, as a result, the ability of the lens to resolve fine details in the specimen is much lower, too.
