A numerical aperture (NA) controlling unit and a variable optical probe including the same are provided. The NA controlling unit includes: an aperture adjustment unit which controls an aperture through which light is transmitted; and a focus control unit that is disposed in a predetermined position with respect to the aperture adjustment unit, that focuses light transmitted through the aperture, and that has an adjustable focal length. The variable optical probe includes: a light transmission unit; a collimator that collimates light transmitted through the light transmission unit into parallel light; an NA controlling unit that focuses light on a sample to be inspected; and a scanner that varies a path of light transmitted through the light transmission unit such that a predetermined region of the sample is scanned by light that passes through the NA controlling unit.

Provided are a wafer-level lens module and an image pickup module including the same. The wafer lens module includes a plurality wafer-scale lenses. At least one of the plurality of wafer-scale lenses, such as a wafer-scale lens positioned toward an object side, includes a substrate and a glass lens element formed on one side of the substrate. The glass lens element may be a one-sided lens or a double-sided lens. When the glass lens is a double-sided lens, the substrate may have a through hole. The remaining wafer-scale lenses each include a substrate and polymer lens elements made of UV curable polymer and formed on both sides of the substrate. Also, spacers are interposed between the wafer-scale lenses, along the edge portions of the substrates, so as to maintain predetermined intervals between the wafer-scale lenses.
