Abstract: A patterning device pre-alignment sensor system is disclosed. The system comprises at least one illumination source configured to provide an incident beam along a normal direction towards a patterning device. The system further comprises an object lens group channel along the normal direction configured to receive a 0th order refracted beam from the patterning device. The system further comprises a first light reflector configured to redirect the 0th order refracted beam to form a first retroreflected beam. The system further comprises a first image lens group channel configured to transmit the first retroreflected beam to a first light sensor. The first light sensor is configured to detect the first retroreflected beam to determine a location feature of the patterning device.

Abstract: An objective lens system having a high numerical aperture, a large working distance, and low optical aberrations over a wide spectral band of wavelengths is disclosed. The objective lens system includes a first lens group, a second lens group, and a third lens group. The first lens group includes first and second positive meniscus lenses that are positioned at a distance from each other along an optical axis of the objective lens system. The distance may be dependent on a focal length of the objective lens system. The second lens group includes first and second meniscus lenses and a bi-convex lens. The third lens group includes a bi-concave lens and a doublet lens.

Abstract: Systems and methods for inspection are provided utilizing a wide angle optical system. The optical system includes a wide angle input lens group and an output lens group. The wide angle input lens group is configured to receive wide-angle radiation, e.g., having an angular spread of 60 degrees or more, from an object surface, and produce imageable radiation. The wide angle input lens group is arranged such that no intermediate focused image is formed within or after the wide angle input lens group. The output lens group is configured to receive the imageable radiation from the wide angle input lens group and focus the imageable radiation onto an image plane to image at least part of the object surface. A detector receives the image of the at least part of the object surface and, based on the received image, detects, for example, contamination on the object surface.
