The achromatic condenser usually contains four lens elements and has a numerical aperture ranging from 0.95 to 1.4. This condenser design is useful for both routine and critical laboratory analysis with "dry" or oil immersion objectives and also for black and white or color photomicrography and digital imaging.

The general rule is that depth of field is inversely proportional to the numerical aperture, which is the size of the opening of an optical component where light passes through- in this case, the objective lens.

Where the far-field pattern is represented by a lens, care should be taken that, especially with high apertures, the diameter of the relay lens, L2, is sufficiently large so as to avoid darkening the periphery: D12 > 2 Higher values of numerical aperture permit increasingly oblique rays to enter the objective front lens, which produces a more highly resolved image and allows smaller structures to be visualized with higher clarity. Illustrated in Figure 1(a) is a simple microscope … This lens has a long working-distance providing ultra-deep imaging with maximum clarity and contrast.
Numerical aperture is an important concept in understanding how light microscopes resolve images and how you can avoid empty magnification. In microscopy numerical aperture is the ability of an objective lens to collect and accept incoming light condensed into a cone of light from the condenser. Numerical Aperture (NA) = n (sin µ) where n is the refractive index of the imaging medium between the front lens of the objective and the specimen cover glass, a value that ranges from 1.00 for air to 1.51 for specialized immersion oils. Many authors substitute the variable α for µ in the numerical aperture equation. Numerical aperture (NA) refers to the cone of light that is made from a focusing lens and describes the light gathering capability of the lens (similar to f/#). NA is defined by the following equation, where n is the index of refraction of the medium (often n=1 for air), and α is the half angle of the cone of light exiting the lens pupil.

Working distance: 5.5 mm; Numerical aperture: 0.5; Chromatic aberration correction: from visible to infrared. Intensity distributions of a tightly focused evanescent field generated by a center blocked high numerical aperture (1.65) objective lens are investigated by a scanning near-field optical microscope. The pure focused evanescent field is mapped and a splitting phenomenon of the focal spot along the direction of polarization, caused by depolarization, is observed not only on the interface, where In this article, issues associated with the microscope-specific parameters NA, M, and R are discussed with respect to both widefield and laser scanning confocal.

Silicone Immersion Objectives Answer the Call for Higher
This condenser design is useful for both routine and critical laboratory analysis with "dry" or oil immersion objectives and also for black and white or color photomicrography and digital imaging. In order to scan a line, the scanning optics usually employs either NSG's SELFOC lens or a 1:1 lenslet array. 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 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.
