ABSTRACT:
A borescope (FIGS. 1 and 4) comprises an objective probe (2) connected to a body (8), an occular assembly (12) pivotally connected to the body so as to be pivotally movable about a pivotal axis (16) extending transversely with respect to the objective probe, and an optical fibre bundle (53) connected to a light source (19) and extending through the probe to illuminate an object presented to the probe. The occular system comprises a housing (11) pivotally connected to the body and cooperating with the body to define a channel (50) through which a flexible portion of the optical fibre bundle extends from the occular assembly into the body whereby pivotal motion of the occular assembly is accommodated by flexure of the optical fibre bundle within the channel. A tubular pivot member (34) is connected to the body and defines the pivotal axis. An optical system (44) consists of a series of lenses (45) and mirrors (37, 47) for transferring an image of the object through the probe to an eyepiece (17) of the occular system and defines an optical axis (46) extending through the tubular pivot member coaxially with the pivotal axis, and wherein the channel comprises an annular space (50) external to the pivot member. The borescope is suitable for use in vehicle body and engine inspection.
