<p>The endoscope is particularly for examination of the larynx, having a telescopic viewing tube to enlarge the object, close alongside and parallel to which is a further viewing tube. The second tube (2) is telescopic also, and can have a wide-angle lens (3). The lenses (4, 5) of both tubes (1, 2) can have a common eyepiece (6). The tube with the wide-angle lens can have a ray divider (5) for a seeker or co-observation eyepiece.</p> |
