Patent ID: 8767060

Claim:
A visual inspection apparatus comprising: a two dimensional image sensor and associated optics for focusing an image of a target substrate onto said two dimensional image sensor; a display, wherein said inspection apparatus is configured to display representations of images focused on said image sensor on said display; a portable handset having a front, a top, a rear, and a pair of sides, said display being disposed at said top, said visual inspection apparatus having an elongated inspection tube extending from said handset, said portable handset being delimited by a hand held housing included as part of said portable handset; image processing circuitry for processing of image data representing light incident on said image sensor; a light source bank for illumination of said target substrate, said image processing circuitry and said light source bank being disposed internal to said hand held housing; an elongated inspection tube extending externally of said hand held housing and being adapted to transmit light generated by said light source bank for illumination of said target substrate; and a heat sink assembly comprising thermally conductive material, said heat sink assembly having a first multi-finned heat sink member and a second multi-finned heat sink member both extending from said hand held housing and having an exposed section exposed to an exterior of said hand held housing, wherein said first multi-finned heat sink member forms part of a first thermally conductive path between said first multi-finned heat sink member and said light source bank, and wherein said second multi-finned heat sink member forms part of a second thermally conductive path between said second multi-finned heat sink member and one or more components of said image processing circuitry.
