[. . . ] For the Axiolab Pol, the universal rotary stage is equipped with a special stage carrier (Fig. Observation and measurement is generally possible in the orthoscopic and the conoscopic mode. With the help of one rotary and two tilting axes (stage 1), the threeaxis universal rotary stage is suitable for aligning a crystal, which normally is birefringent, in any defined direction relative to the optical axis of the microscope. The major fields of application of the universal rotary stage can be classified into three categories: Reinhard [10] and Sarantschina [12] have introduced different definitions. [. . . ] 4/17 and 22) condenser stop so that the condenser will not hit the stage (see manual). whether the spacer ring H"0"M 27 on W 0. 8 (4549109) has been screwed into the fixed (not centerable) nosepiece eye. (Screw in if necessary. ) Screw the UD Achromat 20x/0. 30 Pol in this nose-piece eye, screw in the other objectives so that one eye is left vacant between each of them. Use dust caps to close the vacant nosepiece eyes. Screw the UD Achromat Pol objectives (Fig. 1/3, Adjust the vertical 4, 5) into the nosepiece, always leaving one nosepiece eye between each objective vacant. Use dust caps to close the vacant nosepiece eyes.

Before doing so, adjust the polarizer and the analyzer so that they are at a 90° angle to each other. Align the upper /4 plate to the lower one until dark position is reached without adjusting the objective. Circularly polarized light can be used in conjunction with the universal rotary stage to precisely measure the angle of the optical axes 2 V in birefringent, optically biaxial crystals, for example. If you wish to work in linearly polarized light, remove the two /4 plates from the beam path. For details on the use of circularly polarized light, please refer to Zschach [15]. Note: Example 3: Measuring the angle 2 V of the optical axis of a biaxial crystal in circularly polarized light Proceed as described in example 2 (steps 1 to 10). The axial directions can be identified by the two circular, dark zones with the exit point of the optical axes in their centers . If only one optical axis is located within the tilting range about A4, proceed as described in example 1.

If the thickness of the object carrier and the object differs, the segments and the sample can be vertically adjusted. 5. 2 Objectives Examinations using the universal rotary stage can only be performed with the newly computed Achromat objectives which are screwed into the objective nosepiece direct, without any adapter. The engraved magnification and aperture figures apply when used in conjunction with the segment pair nD = 1. 556. [. . . ] The annular groove for the lower segThe ment and the guideway for the Schmidt rulers must be cleaned very thoroughly due to the high-precision fit to eliminate the possibility of functional defects. smoothness of the vertical objective adjustment must be checked at regular intervals. rotary stage and all accessories in the storage container supplied.
