  • Variable incidence oblique illuminator device
    Patent number: 7357529
    Abstract: The objective lens assembly of an optical inspection device is surrounded coaxially of its optical axis by an illuminator housing having therein a central opening surrounded by a circular array of reflective mirror surfaces or facets that are inclined at like angles to the optical axis, and which register with the light emitting of a like circular array of LEDs mounted in the housing in radially spaced, coaxial relation to the mirror facets. Mounted coaxially beneath the illuminator housing for vertical adjustment relative thereto is a generally disc-shaped Fresnel lens. The lens is movable by drive means optionally between an uppermost position adjacent the underside of the housing and a lowermost position adjacent the work that is to be inspected.
