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 () comprises a body () 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 () and an ocular lens (). A beam splitter () is mounted in the optical path between the relay lens () and the ocular lens () and diverts a proportion of light received from the relay lens () to an image-to-video conversion device () mounted laterally to the optical path. The ocular lens (), beam splitting device () and the image-to-video conversion device () are all located in a common mounting () which can be translated in a direction parallel to the optical path to allow for focussing.
