metallographic microscope light calibration is to center the light source and make the light irradiation more uniform. Please listen to Xiaobian slowly on how to adjust it. Before light calibration, the direction of the microscope and the light source should be adjusted first. In order to make the light source align with the plane light collecting mirror of the microscope, and then adjust the light. After the above steps are completed, the following operations are as follows:

Before light calibration, the direction of the microscope and the light source should be adjusted first. In order to make the light source align with the plane light collecting mirror of the microscope, and then adjust the light. After the above steps are completed, the following operations are as follows:
1, put a slide on the stage, and the condenser moved down after the slide specimen, in order from low to high stop focusing.
2. To focus clearly on the slide specimen, the condenser can be slightly raised in order to obtain sufficient illumination.
3. Close the aperture on the light source to the minimum. Carefully rotate the condenser group under the stage until the reduced aperture is focused on the same plane as the slide, taking care not to focus on the microscope itself.
4. When the metallographic microscope has the function of concentrating the condenser, the condenser can be adjusted to the center of the field of view by moving the image with the aperture narrowed.
5. Open the aperture ring until the polygonal aperture ring just fills the field of view.
6. If possible, remove one eyepiece. Close the iris aperture of the condenser under the stage and look into the tube to observe the object lens. The ray should now appear symmetrical. In research microscopes, one can adjust for any asymmetry at this stage.
7. Open or close the iris aperture on the condenser under the small stage to make only 2/3 of the field of view of the objective lens present light. Put the eyepiece back. At this time, the system has been completed, and the microscope can be used for microscopic examination of slides.
after the above introduction, the gold-phase microscope light adjustment is not understand it, in this also mention everyone, in the process of light in the light do not move the collection mirror, the ideal control method is to use a neutral filter.
