Abstract
An elongated enclosure includes a number of apertures through which a film must be precisely viewed. A slider receives a removable film holder into which a film, such as a 35 mm slide is positioned. A precision recirculating bearing assembly provides accurate and smooth motion of the slider within the housing. A number of alignment components are located in the device to repeatedly and accurately position the film, relative to the apertures. Thus, a laser beam or optical axis can repeatedly and precisely pass through the same point of the image as it appears in a corresponding aperture.
