  • Patent number: 3932022
    Abstract: A light guide arrangement in which at least two light guides are coupled at one end to an optical integration Chamber for achieving a common field of view from the remote ends of both or all of the light guides even when the end of the optical integration chamber is in contact with a surface being scanned, in which the components of the optical integration chamber, that is a light guiding element, a sheath of optically insulating material, and an outer cladding are held together by a bond which does not involve the use of a bonding material, to attenuate the problems due to wear of the scanning end of the optical integration chamber. The scanning tip of the integration chamber may be drawn to a point during or after the bonding to form a well defined scanning point.
