Comments p.1378 right column,2nd paragraph:"The increase in resolution, relative to conventional optical imaging, approached by confocal imaging is only a factor of ~2 in the x, y and z dimensions (Table 1). Yet confocal microscopy has transformed fields from biology to semiconductor manufacturing—highlighting the importance of even moderate improvements in the resolving power of light."
