摘要:
An optical system including a light source, optics for directing illumination, thereby producing reflected light, optics for receiving the reflected light, a splitter disposed at a pupil plane for receiving the reflected light and splitting it into a first and second portion, first imaging optics for receiving the first portion and directing it to a first sensor to produce a first image portion, the first sensor delivering the first image portion to a processor, second imaging optics for receiving the second portion and directing it to a second sensor to produce a second image portion, the second sensor delivering the second image portion to the processor, and the processor for combining the first image portion and the second image portion into a single image of the sample.
