Abstract: An apparatus for measuring a distance such as, for example, a fly height distance. An apparatus includes a slider having an air bearing surface and an optical condenser assembly spaced apart from the air bearing surface of the slider. The optical condenser assembly includes an optical cap and an optical substrate having a first surface and a second surface. The first surface is spaced apart from the optical cap and the second surface is spaced apart from the air bearing surface of the slider.
