  • Patent number: 4470670
    Abstract: A method and device for providing point of contact light or target on a work piece are provided which are particularly adapted for use with a wire bonder independent of the operator's viewing aid and which employ a high intensity light source to create a naturally colored beam of light. In accordance with one embodiment of the invention, a helium-neon laser beam is expanded and then formed into a point of light which is projected onto the work piece surface by an adjustable mirror arrangement which is positioned to reflect the specular component of the beam away from the operator's viewing sight line and which enables easy focusing and adjustment of the target spot so as to substantially reduce parallax.
