Abstract

1,233,606. Endoscopes. OLYMPUS OPTICAL CO. Ltd. 7 Aug., 1968 [8 Aug., 1967 (3)], No. 54374/70. Divided out of 1,233,604. Heading A5R. The subject matter of this Specification is contained in the Specification 1,233,604 but the claims are concerned with an endoscope having a fixed magnification objective lens system, there being means permitting the actual dimension of an object being viewed to be determined despite variation in the distance of the object from the end of the endoscope.
