Abstract
This invention involves a fiber probe device and a method of making it. The probe includes a relatively thick upper cylindrical region, typically in the form of a solid right circular cylinder, terminating in a tapered region that terminates in a relatively thin lower cylindrical region (tip), typically also in the form of a solid right circular cylinder, the lower region having a width (diameter) in the approximate range 0.01 .mu.m to 150 .mu.m.
Claims14
A probe device comprising:
- a fiber segment having a relatively thick upper cylindrical region terminating in a tapered region that terminates in a relatively thin right cylindrical lower region;
- the lower cylindrical portion having a maximum width in the approximate range of 0.01 .mu.m to 150 .mu.m and terminating at its bottom extremity in an essentially planar end surface oriented perpendicular to the axis of the thin right cylindrical region.

- the fiber segment having at most one other right cylindrical region, said at most one other right cylindrical region being located above the thick upper cylindrical region,
- said at most one other right cylindrical region, said thin right cylindrical lower region, and said relatively thick upper cylindrical region having respective maximum widths that are mutually different from each other.
