At the image side, you could use the effective focal and the ideal collimated beam diameter (or pupil size) of 4mm to estimate a numerical aperture.

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 Theoretical analysis of numerical aperture increasing lens microscopy S.

Ünlü Departments of Physics and Electrical and Computer Engineering and the Photonics Center, Boston University, 8 Saint Mary’s Street, Boston, Massachusetts 02215 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 The F-number or numerical aperture defines the amount of light that can pass through the lens set-up.

Such a lens can be placed in the working distance required (see Supplementary When utilizing scanning confocal systems with an electronic zoom feature, it is seldom necessary to employ 100x optical magnification, and the highly corrected (and high numerical aperture) 40x and 60x objectives may be more suitable in techniques benefiting from the additional light collection. resolution for laser and measurement applications (fewer than 10 μm) and high numerical aperture. Furthermore the scanning lens will be designed considering the overall optical aberration effects on the measurement beam, which should be kept minimal. The remaining effects will be compensated using the beam shaping unit, developed in Task 2.5. f/# and Numerical Aperture. It can often be easier to talk about the overall light throughput as the cone angle, or the numerical aperture (NA), of a lens. The NA of a lens is defined as the sine of the angle made by the marginal ray and optical axis in image space, shown in Figure 1.
