Abstract: A focusing apparatus for use with an optical system having a high NA objective lens includes an image forming and capturing mechanism for forming an image in an intermediate image zone and for capturing an image by receiving and refocusing light from a selected focal plane within the intermediate image zone, and a focus adjusting mechanism for adjusting the position of the selected focal plane within the intermediate image zone. The image forming and capturing mechanism includes at least one high NA lens. In use, spherical aberration introduced by the high NA objective lens is reduced.

Abstract: The wavefront sensing device consists of a light source, a binary phase mask (10), a fixed focus lens (11) and at least two finite sized spatially separated detectors (12) positioned in the plane of focus of the wavefront sensing device. The binary phase mask (10) simultaneously applies a positive bias and a negative bias to the wavefront of the incident light such that a pair of spatially separated light points are generated in the plane of focus and detected by the detectors (12). The difference in intensity between the pair of light points is representative of the aberration of the wavefront of the incident light from the ideal.
