Abstract: A correction mask for an optical beam homogenizer includes a lens array. The correction mask is configured to provide a shaped initial beam profile. A subset of a plurality of optical paths between the incoming light beam and the illumination plane is at least partially blocked by the correction mask to provide a further homogenized beam profile having a further reduced light intensity variance with respect to an initial homogenized beam profile. The mask includes a plurality of submasks arranged according to a mask grid layout matching the lens grid layout of the lens array. Each one of the submasks is designed with a specific submask pattern to shape the respective subarea of the initial beam profile passing a specific one of the lenslets.

Abstract: A diffuser system (100) and method for optically diffusing a light beam (L1,L2). At least two transmissive diffuser windows (11,21) are provided. The diffuser windows (11,21) are arranged to sequentially diffuse the light beam (L1,L2) transmitted there through. The diffuser system (100) is configured to continuously rotate the diffuser windows (11,21) at an angular velocity (?1,?2) for homogenizing a diffusive pattern of the transmitted light beam (L1,L2). The diffuser windows (11,21) are configured to rotate around distinct rotation axes (C1,C2). The distinct rotation axes (C1,C2) are parallel and offset with respect to each other by a radial center distance (d12). A rotating subarea of the first diffuser window (11) partially overlaps a rotating subarea of the second rotating diffuser window (12) The partially overlapping rotating subareas define a beam window (W12) for homogenizing and diffusing the transmitted light beam (L1,L2).

Abstract: A component placement apparatus includes: a tray storing device for storing at least one tray that contains, e.g., components; a buffer on which components picked-up from the tray, by means of a first component pickup and placement device, may be temporarily stored; and a second pickup and place device for picking-up a component from the buffer and placing the component on a substrate.

Abstract: Method of determining the position of at least one supporting pin for supporting a side (15) of a substrate (14) in a component placement machine. In a first step of the method, the supporting side (15) of the substrate is made at least partly visible. Next at least one frame (25, 26, 27) is positioned opposite said supporting side (15) of the substrate, said frame comprising at least one fastening element for an auxiliary pin (28). Subsequently the auxiliary pin is arranged in the frame in a removable way in a position in which one end of the auxiliary pin makes contact with the supporting side of the substrate. The obtained position is used as the desired position of the supporting pin.
