User manual LEICA TL RCI

[. . . ] User manuals and updates are also available for download and print-out on our homepage at www. stereomicroscopy. com. The TL RCTM and TL RCITM transmitted-light bases are a module of the Leica M stereo microscope series. This user manual describes the special functions of the transmitted-light base and contains important instructions for operating safety, maintenance and the accessory parts. The M2-105-0 user manual for the Leica M stereo microscopes contains additional safety rules for the stereo microscope, accessories and electrical accessories, as well as instructions for maintenance. [. . . ] Push the cross-stage all the way back to the fence in direction of the column. Re-insert the glass plate back into the standard stage. 3. 1 Unpacking the base The base is delivered with the adapter plate attached. The selected stage (IsoProTM crossstage or standard stage 10 447 269), and the focusing drive will have to be mounted later. Insert the power cable into the mains socket (4. 2), and then connect it to a grounded outlet. TL RCTM and TL RCITM transmitted-light bases ­ Configuration 11 Operation 4. 1 Switch for adjusting the relief contrast Use the two switches (8. 1 and 8. 2) on the left side of the transmitted-light base TL RCTM/TL RCITM to actuate the two integrated flaps. Depending on the flap position, part of the opening of the integrated Fresnel lens is covered causing different contrast effects. Phase structures typically appear as spatial, relief images ­ like hills in a positive relief contrast and as recesses in inverted relief contrast. The contrast can be increased without relief by adjusting the two diaphragms to 45°. The slot can be moved over the entire field of view and quickly switched between positive and negative relief view by precise tilting of the path-folding mirror. The dynamic effect makes it simple to distinguish phase structures from amplitude structures. Using the black rotary knob (8. 1) on the left side of the transmitted light base you can turn and push the path-folding mirror back and forth. The concave recess at the grip shows the concave side of the mirror and allows the intuitive operation without eye contact at anytime. Depending on the angle and position of the mirror the angle of light incidence changes on the specimen level so that you can move between a transmitted light bright field, through oblique illumination to dark field like illumination. The black rotary knob (8. 1) on the left side of the transmitted-light base is used: ­ To rotate the path-folding mirror from the flat to the concave side ­ For slight tilting, to steer the light beam more steeply or flatly through the object level ­ To shift the path-folding mirror (forward/ backward) Depending on the properties of the object (refractive index to environment) and your own sensitivity, it may occur that you need to operate the switches for the positive and inverted relief contrast in reverse. instead of the top switch (8. 1), the bottom switch (8. 2) controls the inverted relief contrast. Instead of the bottom switch (8. 2), the top switch (8. 1) controls the positive relief contrast. 4. 3 Operating the cross-stage IsoProTM To move the stage in X direction rotate the outer knob (7. 1) To move the stage in Y direction rotate the inner ring around the knob (7. 2) 4. 4 Light intensity and color temperature 4. 4. 1 Transmitted-light base TL RCTM Please observe the user manual and in particular the safety regulations of the manufacturers of the light guide and cold light source. Turn on the cold light source according to the manufacturer's user manual and connect, activate, and adjust the light intensity. 4. 2 Path-folding mirror The built-in path-folding mirror features a flat and a concave side and can be rotated and moved. The concave side was specifically designed for the optical features of objectives with high 12 TL RCTM and TL RCITM transmitted-light bases ­ Operation 1 Fig. 8 1 2 1 Switch to control the inverted relief contrast 2 Switch to control the positive relief contrast 3 Path-folding mirror 1 Potentiometer Control of IsoColTM illumination intensity 2 Potentiometer Control of dye temperature 4. 4. 2 TL RCITM transmitted-light base The TL RCITM transmitted-light base has two electronic potentiometers to control the dye intensity (9. 1), and dye temperature (9. 2) separately. Adjust the dye intensity using the front potentiometer (9. 1) to match your requirements. With the rear potentiometer (9. 2), set the dye temperature to match the color impression to your requirements. The dye temperature control also serves as electronic shutter: For process interruption, press the potentiometer (9. 2). The electronics return to the previously selected settings. 4. 5 Leica USB mouse (TL RCITM only) The Leica USB mouse controls the IsoColTM and the dimming function of the TL RCITM base . · By default, the scroll wheel of the mouse is assigned to the IsoColTM control.
