5-3 Conoscopic Observation

FIg. 32

} Use 20X to 100X objectives.

1. Engage the analyzer and adjust for extinction position.

2. Swing the condenser top lens into the light path.

3. When using the intermediate attachment conoscopic and orthoscopic

observation U-CPA, push in the Bertrand lens knob to engage the

Bertrand lens into the light path.

4. Engage an objective of your choice (20X to 100X).

5. Open the aperture iris diaphragm.

6. Slide the focusing knob on the U-CPA to focus on the conoscopic image.

} When the intermediate attachment conoscopic and orthoscopic

observation U-CPA is not used, conoscopic observation is possible

by removing an eyepiece from the observation tube and looking at

the rear focal plane of the objective directly.

} To obtain good image contrast, place an interference filter (45IF546)

in the filter holder on the light exit of the microscope.

} If the periphery of the conoscopic image is dark, move the condenser

vertically to find the position where the periphery is brightest.
