ABSTRACT:
An apparatus for combining optical images which is particularly suited for use in integrated circuit lead wire gang bonding systems is disclosed. The apparatus includes an objective lens to gather and focus light rays reflected from an object, such as a microelectronic device. A beamsplitter provides first and second images of the object which are inverted with respect to one another. The images are directed onto mirrowed prism surfaces, such that only selected portions of the first and second images actually strike each prism face. That portion of each image which does strike the respective prism face is reflected upward and combined to form one resulting image. Viewing means are provided to view the resultant image.
