INSPECTION DEVICE AND INSPECTING METHOD FOR SPATIAL LIGHT MODULATOR, ILLUMINATION OPTICAL SYSTEM, METHOD FOR ADJUSTING THE ILLUMINATION OPTICAL SYSTEM, EXPOSURE APPARATUS, AND DEVICE MANUFACTURING METHOD
First Claim
1. An inspection device for inspecting a spatial light modulator having a plurality of optical elements arrayed two-dimensionally and controlled individually, said inspection device comprising:
- a conjugate optical system which is arranged optically downstream the spatial light modulator and which forms a conjugate plane optically conjugate with an array plane where the plurality of optical elements are arrayed;
a photodetector having a detection surface arranged on or near the conjugate plane; and
an inspection unit which inspects optical characteristics of the plurality of optical elements, based on a result of detection by the photodetector.
