Insert a screwdriver behind the spring clips and extract the fuse holder . Insert the fuses (2×T3, 15AH250VF1/F2). 14 Refit the fuse holder Adjusting the mercury vapour lamp This adjustment is important for obtaining a uniform light spot and good-quality fluorescence . While adjusting the mirror image, do not project light on to the electrodes for long periods (risk of explosion through overheating) The two electrodes are imaged as an extension of the plane of symmetry of the discharge arc, but are difficult to see . Switch on the supply unit and wait for two or three minutes · The100Wsupplyunitemitsawhistle Swing out the UV-light excluder (page 21) · WorkwithouttheUV-lightexcluderisonlypermittedforadjustment, and then only for short periods Pull out the light stop (see page 16, MZ10 F and page 22, Fluorescence module) . MZ10 F: Turn the filter set in the beam path (page 16) . Stereo-fluorescence module: Insert the excitation filter (page 22) . Mark a cross on a piece of paper and place it in the middle of the illuminated spot Select the lowest magnification · Thedischargearcisvisibleintheilluminat dspotandlies e at about 45° to the lines of the cross (fig . a) Look into the eyepieces and focus on the cross Using your unaided eye, observe the discharge arc on the paper and bring it into focus with the focusing knob (3) (fig . a) Using the positioning knobs (1 and 2), displace the discharge arc (fig . b) Bring the mirror image of the discharge arc into focus with the knob (6) and use the knobs 4 and 5 to position it symmetrically relative to the original image (fig . c) · Forthe50Wburner, thedischarge-arcmageandits i mirror image should touch · Forthe100Wburner, thedischarge-arcmageanditsmirror i image should be superimposed .

Filterholder fluorescence module The dichromatic beam splitter and the barrier filter are built into the fluorescence module in accordance with the configuration (see table, page 19) . The excitation filter is supplied in a separate filterholder . A filterholder with diaphragm is also supplied . This diaphragm can be slid into the illumination beam path if the object should not be illuminated . 3 12 Slacken the central fixing screw . [. . . ]
