    摘要: A projection exposure device (1), in particular for micro-lithography, serves to produce an image of an object (2) in an image plane (11) positioned in an object plane (10). For this reason the projection exposure device (1) has a radiation source (4) emitting projection radiation (5). Illumination optics (6) are positioned between the radiation source (4) and the object plane (10) and projection optics (8) are positioned between the object plane (10) and the image plane (11). A detection device (30) is provided to measure the illumination angle distribution of the projection radiation (5) in a field plane (10). This communicates via at least one control device (34, 18) with at least one manipulator (20, 45, 47). The latter serves to move at least one optical component (7, 41) within the projection ray path (5, 9). The illumination angle distribution changes as a result of the controlled movement of the optical component (7, 41). This can therefore be adjusted depending on the measurement result and for example adapted to the object structure.

    摘要: A device for the magnified viewing of an object, from which object rays originate, includes a lens system (1) for collecting object rays. In one embodiment of the invention, the device includes: a display (2) from which display rays (14) originate, and; a left eyepiece (3) and a right eyepiece (3), via which a left-eye and right-eye beam (5 and 6) of visual field rays are projected into the left and right eye of a user of the device. According to this inventive embodiment, an optical component (7, 8, 9, 10, 11) is provided with a physical ray distributing surface (12) on which a beam of collected object rays (13) and a beam of display rays (14) can be superimposed and can be divided up into the left-eye beam and right-eye beam (5, 6) of the visual field rays. This enables a reduction in losses of display rays and object rays.

    摘要: A laser system has an output/input coupler unit (49) with a circulator (37). An output of the circulator (37) is operationally connected to a detector unit (43). The input/output (EA37) of the circulator is operationally connected to a transmitter and a receiver optics 41. Laser light is input to the circulator (E37). The input (E37), output (A37) and output/input (EA37) of the circulator are optical fibers. The pulsed diode (3) is not temperature stabilized. To reduce amplified spontaneous emission (ASE) generated in the optical fiber amplifier (9), a narrow band-pass filter unit (29) is used. Filter unit (29) has a central wavelength with a temperature dependence which is matched to the temperature dependent wavelength shift of the pulsed diode (3).
