ABSTRACT:
A positioning and targeting apparatus is attached to a beam emitting source having a beam central axis. The apparatus has an attachment collar enabled for securement to the emitting source. A lateral supporting member is engaged with the attachment collar and extends in an axial direction. A radial supporting member is engaged with the lateral supporting member and terminates on the beam central axis. A pointer is, in turn, engaged with the radial supporting member and positioned along the beam central axis. The pointer provides at least one axially telescoping segment and a locking nut for fixing the telescoping segment at a selected telescoping position relative to a base segment of the pointer. The radial supporting member and the pointer are made of material invisible to the source's beam.
