摘要:
A camera adaptor (19) is provided for connecting a camera (21) to an interface (13) of a medical-optical observation instrument (1) with a parallel beam path. The interface (13) is situated in the parallel beam path (9a, 9b) of the medical-optical observation instrument (1). The camera adaptor (19) has an instrument connector part (41) for connection to the interface (13) of the medical-optical observation instrument (1) and a camera connector part (43, 143) for connection to a camera (21). The beam path (43) runs through the camera adaptor (19) along a linear optical axis. The camera adaptor (19) has an objective-lenses combination (47) with a total focal length between 40 mm and 120 mm. A lens with a positive partial focal length leading on the instrument side in the objective-lenses combination (47) and is followed, on the side toward the camera, by a lens with a negative partial focal length.
摘要:
An illumination system (12) of a microlithographic exposure apparatus (10) comprises a condenser (601; 602; 603; 604; 605; 606) for transforming a pupil plane (54) into a field plane (62). The condenser has a lens group (L14, L15, L16, L17; L24, L25, L26, L27, L28; L34, L35, L36, L37; L44, L45, L46; L53, L54, L55) that contains a plurality of consecutive lenses. These lenses are arranged such that a light bundle (70) focused by the condenser (601; 602; 603; 604; 605) on an on-axis field point (72) converges within each lens of the lens group. At least one lens (L15, L16, L17; L25, L26; L34, L44, L45; L54) of the lens group has a concave surface. The illumination system may further comprise a field stop objective (66; 666, 666′) that at least partly corrects a residual pupil aberration of the condenser (601; 602; 603; 604; 605; 606).
