2 Operating Instructions Leica Microscope Room NB Bright field 1. Turn the power on using orange switch on the right-hand side of the base. 2. Pull the Beam Splitter on the upper left-hand side of the scope to 50/50 or Vis. 3. Adjust the light level to 8 by adjusting the Bright-Field Rheostat on the lower left-hand side of the base. 4. Use the correct condenser. One condenser will be mounted on the scope, the other is stored in the top drawer immediately to your left. a. For low magnification objectives (1.25X, 2.5X, 4X or 10X) use the Nikon Achro 0.13 condenser b. For high magnification (20X, 40X, 63X or 100X) use the Leica 0.9 PSI. The condenser is stored in the top drawer to your left. c. To replace the condenser, lower the condenser to the lowest Z positon using the Condenser Z-Axis Focus knob behind the condenser and loosen the silver grub screw on the right side of the condenser and remove the condenser towards you. 5.

When using the high-magnification condenser, be careful to insert the pin on the back of the condenser into the notch at the back of the support. 6. Tighten the grub screw to secure the condenser in place. 7. Establish Kohler Illumination for the high-magnification condenser. a. Raise the condenser to near the top limit without hitting the slide. b. Place a slide on the stage to establish plane of focus using the 20X or 40X objective.

3 c. Close the Field Diaphragm so that you can see it through the objective. d. Adjust the Z axis of the condenser to bring the edge of the leaves of the field diaphragm into focus. e. Open the field diaphragm just beyond the limits of the field of view and then turn the Condenser Iris to match the color of the ring on objective you are using. 8.
