16. Aligning the lamp in the optical path
Aligning the lamp in the optical path is necessary to compensate for the mechanical differences amongst lamps. Since at least part of the process of manufacturing discharge lamps is manual in nature, the position of the arc may vary slightly from lamp to lamp. The alignment process will allow for the maximum output of the lamp to be achieved.
Alignment procedure
Alignment is effected via the three adjusters A , B and C operating in conjunction. Use a Philips head screwdriver for this procedure. The three screws are located on the rear of the projector head. The adjusters act on a lever and spring assembly which position the lamp horizontally and vertically in the reflector. Rotating the screws will move the lamp within the reflector. Alignment should be effected whilst the lamp is on, the blackout fully open and no colour filters or gobos inserted. Rotate the screws until the optimum output is achieved, with both maximum output and the maximum uniformity across the beam. You should ensure that the lamp does not touch the reflector, as this could damage both components.
