    摘要: An assembly is described for connection to a borescope to simultaneously provide a virtual image for direct viewing by an observer and a video image for viewing on a display. The assembly (10) comprises a body (12) with a distal end for connection to an insertion tube of a borescope and a proximal end providing an eye piece into which an observer may look. The body contains a relay lens (16) and an ocular lens (18). A beam splitter (28) is mounted in the optical path between the relay lens (16) and the ocular lens (18) and diverts a proportion of light received from the relay lens (16) to an image-to-video conversion device (30) mounted laterally to the optical path. The ocular lens (18), beam splitting device (28) and the image-to-video conversion device (30) are all located in a common mounting (38) which can be translated in a direction parallel to the optical path to allow for focussing.
