- Page 2 2. Unpacking The PriorLab / PriorLux is shipped in protective bags within a pre-formed container. Each component should be carefully unpacked and checked, cutting rather than tearing the plastic bags. The head (binocular or trinocular) should be fitted to the dovetail on top of the stand and locked in place with the head locking screw.

- Page 5 Electrical Connection and Safety Stands are supplied with an operating voltage of either 220/240 VAC 50/60Hz or 110/120 VAC 50/60Hz. The instrument is supplied with a power lead complete with appropriate plug for mains connection. UK plugs are fitted with a 3A fuse. This should only be replaced with a similarly rated fuse.
- Page 6 Setting Köhler Illumination Follow the procedure in section 6 to set up the instrument for your eyesight. With a specimen in sharp focus using the 10x objective, close the field diaphragm until it impinges on the field of view, Figure 1, Picture A. Figure 1 Focus the condenser using the side mounted rack and pinion controls until the leaves of the diaphragm are in sharp focus, Figure 1, Picture B.
- Page 7 Oil Immersion Objectives Only For oil immersion lenses, make sure that a part of the specimen is in the centre of the field of view as seen with the last dry objective used. Rack the nosepiece up slightly, swing the dry lens to one side, rotate the 100x oil immersion lens over the specimen ensuring that it clears the cover-slip.
- Page 8 Phase Contrast Figure Phase contrast is a technique used to amplify contrast in unstained samples. To be able to see objects with phase contrast the optional phase kit is required. This includes a phase turret condenser (see figure 2), phase objectives, a centering telescope and a green filter. Firstly the standard condenser must be removed by loosening the retaining screw and the phase turret condenser installed in its place.
- Page 9 Figure 3 This procedure needs to be carried out for every objective, but unless deliberately adjusted should not need checking again frequently. If the quality of the phase contrast image is poor then check that the condenser is properly focused and centred and then ensure that the rings are correctly aligned.
- Page 10 Using a Camera The PriorLab / PriorLux microscopes, when fitted with a trinocular head, can be used with a range of cameras for documentation purposes. Video cameras, both analogue and digital provide ‘moving’ pictures for more advanced imaging applications, while digital ‘still’...
