A new technique, to the best of our knowledge, for improving the axial resolution and imaging contrast of a reflection mode confocal microscope is proposed. A 50 µm silica microsphere is added in front of the objective lens to enhance both the focusing of illumination and the collection of reflected and scattered light from sample surfaces in noncontact mode. An adjustable pinhole is used to compensate the displacement of the focal point in the axial direction. Various samples, including grouped nanolines and nanosteps, are used to demonstrate
