Scanning in (or close to) the objective lens pupil elim-inates the need for a relay telescope between the scanner and the objective lens. This reduces the com-plexity and size of the microscope. Since we do not scan exactly in the pupil plane of the objective lens, Thus, the SEM objective lens is the last lens in the series of lenses that create the electron beam that scans the specimen. This lens focuses the scanning beam to a very small spot. When using a light microscope, focus the specimen with the scanning objective lens first. 6.

The shorter the lens, the lower magnification power it has. •Role of the objective lens The objective lens is used for focusing, and this lens is a very important lens that determines the final diameter of the electron probe. If the performance of the objective lens is not good, an optimally-fine electron probe cannot be produced despite all of the efforts before the action of the objective lens.

In order to fulfill the main objective and cope with the related challenges four work areas / specific objectives were defined and subdivided on working groups, which are lead and executed by partners regarding their expertise. The scanning device comprises a radiation source for generating a radiation beam and an objective lens for converging the radiation beam through one of the transparent layers to a single best focus, and in which an outer annular part of the objective lens introduces a first spherical aberration compensating for passage of the radiation beam through the first transparent layer and a central The target is scanned by the 3D optical metrology device (such as a CLSM) on a 0.5 micron by 0.5 micron by 0.25 micron grid (XYZ). The scanned volume was 15 microns by 12000 microns by 200 microns (XYZ).
