Abstract:

An alignment-target mount for permanent installation along an optical line-of-sight is disclosed. The mount includes a cylindrical body of a nonferrous material, which body, in turn, includes a hollow casing with a longitudinal axis substantially positionable within the vertical plane of the line-of-sight; a plug attachable to the inner casing wall having a rotatably positionable slideway thereacross; an alignment-target base slidably supported by the slideway of the plug and adjustable along a line predetermined by the rotational position of the plug; and a locking device for affixing the target base to the plug. With the basic unit, there is included a demountable target assembly affixable to the alignment-target base. The geometry of the target base is such that the alignment target is supported with the longitudinal axis thereof parallel to the vertical plane with the line-of-sight therewithin. In the arrangement disclosed and with the unit permanently installed, the demountable target assembly is mountable during the use of the optical line-of-sight, demountable therefrom, and remountable on the optical line-of-sight without further adjustment.
