    Abstract: An instrument for measuring the angular distribution of light produced by an illumination system of a microlithographic projection exposure apparatus comprises pinhole (82) and a polarization conversion unit (92), for example a quarter-wave plate, that converts at least one state of polarization of the light into a circular state of polarization. An irradiance sensor (96) such as a CCD image sensor detects the spatial distribution of light having passed the pinhole (82) and being in a circular state of polarization. An aspheric collimating lens (90) may be arranged between the pinhole (82) and the polarization conversion unit (92).

    Abstract: The invention relates to a light beam receiver (1) for analysing the reception of light beams by means of a plurality of light beam detector elements (112, 113) and integrators (141, 142) for light beam element-based signals (161, 162). An integration duration control system (143) having the effect of limiting signal integrality is allocated to at least two integrators. In this way, received light beams can be analysed by their response to evaluated integrator signals (171, 172) that are related to each other.

    Abstract: A zero point adjustment is performed by generating no signal state of a CCD camera. A state in which stray light does not enter the CCD camera is ensured by a calibration shutter. An output signal of the CCD camera is transmitted to a light amount calculator, and a calibrating section executes a calibration for the light amount calculator by using an output signal value as a reference (zero point). Further, light outputted from a laser light source is attenuated by an optical attenuator and is made to be incident on the CCD camera. By switching an attenuating amount of the optical attenuator, correctly set light is made to be incident on the CCD camera. The output signal of the CCD camera is transmitted to the light amount calculator, and the calibrating section executes the calibration such that values of the respective output signals correctly correspond to respective light amounts.

    Abstract: Disclosed is a method for correcting the temperature sensitivity of the amount of light L emitted by a light emitting diode (LED) and measured in a light detector, said LED being operated in a pulsed mode with an essentially constant pulse duration tP. According to the inventive method, a predetermined parameter X that has a predetermined ratio to the temperature T of the LED is used while a corrective factor K is determined from said parameter X, preferably using a calibration table, most preferably a closed, predetermined function, with the aid of which the measured emitted amount of light L is corrected by the temperature-dependent variations of the emitted amount of light. The parameter X is determined from at least two output signals of the LED which are correlated in a predetermined manner.
