Как есть а поляризация микроскоп'с поляризатор калиброванный?
In operation, the vibration directions of the upper and lower polarizers of the polarizing microscope should be perpendicular to each other, or the east-west and north-south directions, which are respectively consistent with the horizontal and vertical directions of the eyepiece reticle. Sometimes only one lower polarizer is used for observation, and the vibration direction of the lower polarizer must be determined, so the polarizer must be corrected during operation.
1. Обнаружение окуляр прицельная сетка
Как правило, , it is необходимо к проверить будет окуляр сетка есть ортогональ и ли это есть в то же вибрация направление as the верхний и нижний поляризаторы. At the same time, select a piece of biotite that has been полностью cleaved, move it to the center of the eyepiece reticle, and place the clevage seam parallel to one of the reticle. record the scale number of the stage, and then turn the stage so that the cleavage seam is parallel to the other cross wire, record the scale number of the stage, the difference between the two scale numbers is 90 degree , indicating that the the cross wire is orthogonal.
2. Determination and correction of the vibration direction of the lower polarizer
3. Orthogonal correction of the upper and lower polarizers
