Stereo-fluorescence module The stereo-fluorescence modul can be combined with the Leica stereomicroscope models MS5, MZ6, MZ7 . 5, MZ9 . 5, MZ12 . 5, MZ16, and with older models . User manual The present user manual describes only the functions of the fluorescence illuminator, the use of the filter sets, and the fitting of the fluorescence module . For detailed information about the use of the stereomicroscope, its care and its safety, please refer to those sections of the separate manual M2-105-0EN which relate to the Leica MZ12 . 5 with 12 . 5:1 zoom . Place of use Leica stereo-fluorescence systems are intended for use in closed rooms and may not be used outdoors . Responsibilities of person in charge of instrument ­ Ensure that the Leica stereo-fluorescence systems are operated, maintained and repaired only by authorized and trained personnel ­ Ensure that personnel who use the instrument have read and understood this user manual and in particular all safety instructions . 4 Servicing and repairs ­ Repairs may only be carried out by Leica-trained service technicians or by technical personnel authorized to do so by the person in charge of the instrument ­ Only original Leica spare parts may be used ­ Unplug the power cable before opening the supply unit . Touching live circuits can cause injury . Supply unit · Pull the power plug of the supply unit out from the power sokket: ­ when assembling and dismantling the lamp housing ­ before opening the lamp housing ­ when changing the mercury-vapour burner and other components such as the heat-protection filter or the collector ­ when servicing the supply unit Legal requirements Adhere to general and local regulations relating to accident prevention and environmental protection . Lamp housing · Never open the lamp housing while the burner is switched on (risk of explosion, UV irradiation, dazzling) Conformity with European Community directive Leica stereo-fluorescence systems and their accessories are constructed in accordance with the latest technologies and are provided with a statement of conformity with EC requirements . · Always allow the lamp housing to cool for at least 15 minutes before opening it (risk of burner exploding) · Never cover the ventilator slots on the lamp housing (risk of fire) Mercury-vapour lamp · Read the user manual and safety directions provided by the manufacturer of the mercury-vapour burner, and particularly those relating to its breakage and to the release of mercury Light source: Safety regulations Safety measures introduced by manufacturer ­ UV protection screen in front of the specimen plane prevents direct UV radiation from reaching the eyes . ­ Dummy filter carriers in the unoccupied positions of the rapid filter changer prevent direct UV radiation from reaching the eyes ­ UV filters in the observation beam paths protect the eyes against UV radiation .

Fuses ebq 100dc 90V to 250V AC, max 265VA 48Hzto63Hz IP20 G 34240090 The fuse holder is secured in the holder with spring clips on both sides . Insert a screwdriver behind the spring clips and extract the fuse holder . 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) .

Use the dummy filter carrier: ­ if you are using less than four sets of filters ­ if you are working without the fluorescence illuminator for periods of up to 15 seconds . · Donotusethedummyfiltercarriertoblockthelightfromthe mercury-vapour burner for more than 15 seconds, or it will heat up . Light stop The FLUOIII filter system includes a slot for the light stop . transmitted light instead of under conditions of fluorescence, the light stop is used to block the illumination beam path so that the mercuryvapour burner does not have its life shortened by being switched on and off more than is absolutely necessary (see page 5) . FLUOIII filter system The filter system consists of a rapid filter changer for the barrier- and excitation filters and two slots for a light stop and for a filter slide respectively . Rapid filter changer The rapid filter changer of the Leica MZ10 F accepts a total of four sets of filters . Each filter set consists of two barrier filters for the observation beam paths and one excitation filter for the illumination beam path . To avoid fingerprints on the filters in the filter sets, try to avoid touching them . If fingerprints do occur, remove them with a clean lint-free cloth and pure alcohol . An empty filter carrier is available for individual filter combinations . Insert a set of filters into the rapid filter changer so that the inscription (e . g .
