Abstract: An optical assembly includes: an optical element, which is transmissive or reflective to radiation at a used wavelength and has an optically used region; and a thermally conductive component, which is arranged outside the optically used region of the optical element. The thermally conductive component can include a material having a thermal conductivity of more than 500 W m?1 K?1. Additionally or alternatively, the product of the thickness of the thermally conductive component in millimeters and the thermal conductivity of the material of the thermally conductive component is at least 1 W mm m?1 K?1.

Abstract: The disclosure relates to a microlithographic projection exposure apparatus, such as are used for the production of large-scale integrated electrical circuits and other microstructured components. The disclosure relates in particular to coatings of optical elements in order to increase or reduce the reflectivity.

Abstract: The present system provides centrally managed licensing where licensed user capacity may flow to where it is most needed. All user capacity may be allocated to the appliances. This provides a much better experience if communication between the central license server is severed from an appliance, as the appliance can still continue to service connections up to that allocated capacity even though it is unable to contact the central license manager. Sublicenses are created from a master license and allocated to appliances. The appliances may provide services based on the licensed set of features and user capacity allocated to them without any further communication with a central server that provided the sub-licenses. The central server may collect information from each appliance and may re-allocate licensed user capacity among the appliances.
