A device and technique for aligning the center of a solid state imager, such as a CCD sensor, to the optical centerline of its respective lens and then using this aligned assembly as a piece of a more complicated electro-optical system uses a target and alignment device. The lens is first place in a connector that is held by a lens support so that the optical center of the lens is at a known point relative to the lens support. Then the lens support structure is placed in from a target device having a pair of crosshairs. The target is positioned so that there will be a line perpendicular to the front face of the lens support which passes through the optical center of the lens and a center of the pair of crosshairs. Next the imager is positioned opposite the back face of the lens support and a cross hair is generated at the optical center of the imager. The imager is then moved in the x and y directions to a position where the generated pair of crosshairs of the image overlays the pair of crosshairs of the target as seen on a display connected to the imager. At that point the imager and the lens are aligned. To complete the procedure the imager is affixed to the lens trough a connector to form the assembled camera lens package. The lens, connector and imager typically will be removed from the lens support and from a lens camera package. Alternatively, the lens support may be included with the lens camera package. |
