이후 the materials observed by an inverted microscope are generally cultured cells, which have high transparency and inconspicuous structural contrast, an inverted microscope is often equipped with a phase-contrast objective lens, which actually constitutes an inverted phase-contrast microscope.
On an inverted microscope, various types of consumables such as Petri dishes and multi-well plates are often used. The thickness of the bottom is different, which will cause certain changes in the passage of light. At this time, it is necessary to use an objective lens with a correction ring function, which is equipped with a ring-mounted adjustment ring in the middle. When the adjustment ring is turned, the distance between the lens groups in the objective lens can be adjusted, thereby correcting the correction caused by the cover glass (petri dish). ) Aberrations caused by non-standard thickness (1.2mm for conventional petri dish, 0.17mm for cover glass). The correct way to use it is: adjust the correction ring to the standard value of 1.2mm, and focus on the sample. Adjust the correction ring to the right by half a grid, and then focus on the sample. If the image effect becomes better, then adjust to the right and then focus, otherwise adjust to the left.
