What do you know about poor microscope coverage
The optical system of the microscope also includes the coverslip. Due to the non-standard thickness of the cover glass, the optical path of the light after entering the air from the cover glass is changed, resulting in a phase difference, which is poor coverage. The generation of poor coverage affects the sound quality of the microscope.
According to international regulations, the standard thickness of the cover glass is 0.17mm, and the allowable range is 0.16-0.18mm. The difference in this thickness range has been calculated in the manufacture of the objective lens. The 0.17 marked on the objective lens housing indicates the thickness of the cover glass required by the objective lens.
