Patent ID: 7298536

Claim:
A fiber optic probe comprising: (a) a probe body having a tip for selectively approaching a device under test; (b) an elongate optical fiber extending longitudinally along said body and extending beyond said tip; (c) said probe body being sized such that at least a major portion of said elongate optical fiber is maintained free from freely moving with respect to said probe body in a direction transverse to a longitudinal axis of said elongate optical fiber when said tip makes pressing engagement with said device under test during testing; and (d) a support that selectively, disengageably maintains said optical fiber from freely moving longitudinally with respect to said probe body, and a collet rotatable with respect to said support, said collet engaged with said elongate optical fiber so as to permit controlled rotation of said fiber while said support maintains said fiber from freely moving longitudinally with respect to said probe body.
