DEFINITION

Classification: 356/241.1

Bore inspection (e.g., borescopes, intrascope, etc.)

(under subclass 237.1) Inspection of imperfections or impurities wherein the specimen is a hole, passage, or generally tube-like structure having a proximal end and a distal end, wherein light is directed to the distal end providing a view of the interior of the specimen from the distal or proximal end.
