ABSTRACT:
A viewing scope is described having a two-part ocular piece which assures that strain due to probe flexing does not build-up and cause breakage in a quartz silica or other similarly rigid fiberoptic image bundle. The ocular piece includes a holder which maintains the image end of the image bundle in a predetermined position with respect to the ocular parts necessary to focus the image, and a body portion to which the outer tubular cover of the probe is secured. The connection between the holder and body allows limited translational movement between the same so that differential longitudinal expansion between the image bundle and the remainder of the probe can be accommodated.
