Web1 jul. 2011 · Edmund Optics’ large-format 4-Mpixel telecentric lenses support up to 28.7-mm-diagonal sensors and offer greater than 40% contrast at 72 lp/mm across the sensor (see Fig. 1). FIGURE 1. Many object-space telecentric lenses such as Edmund Optics’ large-format 4-Mpixel versions are designed for use with 28.7-mm-format sensors. In … WebA superlens, or super lens, is a lens which uses metamaterials to go beyond the diffraction limit.The diffraction limit is a feature of conventional lenses and microscopes that limits the fineness of their resolution depending on the illumination wavelength and the numerical aperture NA of the objective lens. Many lens designs have been proposed that go …

Web12 jan. 2016 · EUV lithography is currently being targeted for insertion at the so-called 7nm mode (λ of 13.5nm and NA of 0.33) to provide a d min of about 13nm (where k 1 is about 0.32). 1 The optics for EUV lithography (see Figure 1) … WebSince lithography for device fabrication involves the use of optical exposure to create the pattern, semiconductor lithography is commonly called "photolithography". As with the inspection and metrology techniques already discussed, photolithography is the technique of choice for patterning because it is optical, and thus enables small features and high …
WebAstigmatism (optical systems) An optical system with astigmatism is one where rays that propagate in two perpendicular planes have different foci. If an optical system with astigmatism is used to form an image of a cross, the vertical and horizontal lines will be in sharp focus at two different distances. The term comes from the Greek α- ( a ...
