7. Start-up

Caution:

In older lamps, the structure of the arc is no longer clearly recognizable. The image is then more like that of a Hg 50 lamp. The im- age and mirror image can no longer be su- perimposed exactly. In this case, align both images.

Using the collector, defocus the image with the knob (30.6) until the arc image and mirror image are no longer recognizable and the im- age is homogeneously illuminated
