[. . . ] Never view directly into these high power lamps!The other regulations for your safety, as detailed in the instruction manuals, must be observed strictly!· Adjust the lamp helix or light source image as described in the above mentioned instructions. · Fit the lamp on the stand as described in Section 2. 1 (4). In doing so, orient the lamp housing perpendicular to the stand so that the lamp mount points downwards (no orientation point available). NOTE When using these lamps, the uniformity of illumination for the lens 2. 5x/0. 075 can be improved by slightly readjusting on the focusing screw (symbol with the horizontal double arrow). Check this with a homogeneously reflecting object (mirror), while observing the illumination and the edge of the field. 2 32 09/95 B 40 016 e Axiolab Pol 2. 7. 3 Replacing condensers 1 6 2 5 4 3 Figure 2 25 Replacing the condenser · Raise the rotary stage Pol to the stop by means of the coarse drive (2 25/2). · Lower the condenser carrier by means of the condenser drive (2 25/1) and undo the clamping screw (2 25/3). IMPORTANT When using the overview unit (445313) or the circular polariser (453623), make sure that the rotary bearings of these units do not press on the luminous field diaphragm (2 25/4). · Pull the condenser towards you out of the guide fork; if necessary, tilt down the front optics (shift lever (2 25/5 or 6)). · Insert the other condenser in the reverse order.

For installation, first secure the screw (2 26/4) at the screw in point (2 26/3) and then the screw (2 26/7) at the screw in point (2 26/2). · First secure the polariser D, rotary (453620) (2 26/14) at the screw in point (2 26/11) using the key (2 26/8) and then secure the latching rod (2 26/10) at the screw in point (2 26/12). · Carry out disassembly in the reverse order. NOTE The polarisers have been optimally aligned at the works. In certain circumstances, slight readjustment analogous to Section 2. 7. 6 may be necessary during the course of replacement. 2 34 09/95 B 40 016 e Axiolab Pol 2. 7. 5 Assembling and using the overview unit, swivelling for lens 1. 25x (accessory 445313 for equipment 0. 4 and 0. 5) For overview observation in a specimen field Ø = 16 mm (when using the Plan Neofluar 1. 25x/0. 04 lens / accessory 440300) in transmitted light bright field or polarisation mode, the above mentioned overview unit is needed to illuminate the field. · To facilitate assembly, detach the rotary stage from the stand as described in Section 2. 7. 1 (3). · Using a screwdriver, first unscrew the fillis ter head screw (2 27/2) on the underside of the polariser D, rotating (2 27/1). · Screw the analogous bearing screw of the large field lens (2 27/4) into the now exposed threaded hole in the rotary bearing of the polariser (use key (2 27/5) to do this). NOTE Re insert the spring washer (2 27/3) on assembly. 1 6 2 3 4 8 5 Figure 2 27 Using the overview unit 7 · Screw on the extended latching rod (2 27/6) analogously to the polariser D, rotating (Section 2. 7. 4) after removing the latching rod (2 27/7). · Insert the condenser as described in Section 2. 7. 3 and raise it by means of the condenser drive (2 25/1). · Position the rotary stage on the stand as described in Section 2. 7. 1 (3) and slide it up until the bottom stop (2 19/3) takes effect, and secure it here.
