    • PROBLEM TO BE SOLVED: To provide a method for manufacturing a projection objective appliance and the projection objective appliance manufactured by this method.SOLUTION: A method for manufacturing a projection objective appliance includes a step of defining an initial design for a projection objective appliance and a step of optimizing the design using a merit function having a plurality of merit function components AB, IRRAD EFP, each of which reflects a specific quality parameter. One of that merit function components defines a maximum irradiance requirement requiring that a normalized effective irradiance value representing an effective irradiance AB, IRRAD EFF normalized to an effective irradiance in an image surface of the projection objective appliance does not exceed a predefined irradiance threshold value IRR TV on each optical surface of the projection objective appliance except for a last optical surface directly adjacent to an image surface of the projection objective appliance. Optical surfaces positioned within caustic regions and/or critically small effective sub-apertures on optical surfaces are thereby systematically avoided.
