  • Patent number: 9632436
    Abstract: An optical assembly including: a beam generating system generating radiation (6) at an operating wavelength, an optical element (13, 14) arranged in a residual gas atmosphere (16) and subjected to the radiation, which induces a degradation of a surface of the optical element, and a feed device feeding at least one gaseous constituent into the residual gas atmosphere, to suppress the degradation of the surface. Either a beam diameter (d) of the radiation at the surface of the optical element, lies above a threshold value (dc), thereby suppressing the degradation by the gaseous constituent, or, if the beam diameter (d) at the surface (14a) of the optical element (14) lies below the threshold value (dc) so that the effectiveness of the suppression of the degradation is reduced, at least one further device (25, 27) enhancing suppression of the degradation of the surface (14a) is assigned to the optical element (14).

  • Patent number: 8856595
    Abstract: A method and a programmable logic controller (SPS) for verifying an application program in a failsafe programmable logic controller, wherein a signature (desired value) is generated using program modules or a complete application program when creating a program, and a copy of the signature is stored in the programmable logic controller and in an external component, respectively. Before the safety-oriented application program is started, the copy of the signature stored by the programmable logic controller is transmitted to the external component and is compared with the copy in the external component. In a further comparison, a signature (actual value) is generated using the content of the main memory of the programmable logic controller and using the actually loaded application program and is then compared with the local copy of the desired value of the signature. Starting of the actual application program is enabled only when both comparisons are positive.
