Technical Examples

We disclose an apparatus and method for detecting probe-tip contact with a surface, generally inside a focused ion-beam instrument, where the probe tip is attached to a capsule, and the capsule is movably secured in a probe shaft. There is a fiber-optic cable having a first end and a second end; a beam splitter having first and second output ports; and a light source connected to the beam splitter. The first output port of the beam splitter is connected to the first end of the fiber-optic cable, and the second output port of the beam splitter is connected to a photodiode. The second end of the fiber-optic cable has a mirror for reflecting incident light at approximately a ninety-degree angle to the axis of the optical path in the fiber-optic cable and onto the capsule, so that the intensity of the light reflected back from the capsule through the fiber-optic cable is proportional to the deflection of the capsule as the probe tip makes contact with the surface.
