Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
211 words
An apparatus for viewing selected portions of an object, comprising: light gathering means for gathering and focusing light rays from said object; a first light reflecting surface; a second light reflecting surface oriented substantially 90 degrees with respect to said first light reflecting surface; beamsplitting means for splitting said light rays into first and second object images, said first and second object images having different spatial orientations such that said second object image is inverted with respect to said first object image; light directing means for selectively directing at least some portion of said first object image onto said first reflecting surface, and for directing at least some portion of said second object image onto said second reflecting surface, such that said first and second object images reflected from said surfaces form a single resultant image; positioning means for selectively positioning said first and second surfaces along an axis defined by the bisector of said 90 degree angle between said surfaces, such that only a desired portion of said first and second object images is directed onto said reflecting surfaces; viewing means positioned above said first and second light reflecting surfaces for viewing said resultant image; whereby selected portions of said object image are combined to form a single resultant image.
Claim 2
Independent Claim
211 words
An apparatus for viewing selected portions of an object, comprising: light gathering means for gathering and focusing light rays from said object; a first light reflecting surface; a second light reflecting surface oriented substantially 90 degrees with respect to said first light reflecting surface; beamsplitting means for splitting said light rays into first and second object images, said first and second object images having different spatial orientations such that said second object image is inverted with respect to said first object image; light directing means for selectively directing at least some portion of said first object image onto said first reflecting surface, and for directing at least some portion of said second object image onto said second reflecting surface, such that said first and second object images reflected from said surfaces form a single resultant image; positioning means for selectively positioning said first and second surfaces along an axis defined by the bisector of said 90 degree angle between said surfaces, such that only a desired portion of said first and second object images is directed onto said reflecting surfaces; viewing means positioned above said first and second light reflecting surfaces for viewing said resultant image; whereby selected portions of said object image are combined to form a single resultant image.
Claim 3
Dependent Claim
20 words
