This means that there might be some spilled over while rotating the objective lens.   Please make sure to clean "all the objective lenses" properly after finishing your work.  Learn from my deposited video if you are not sure how to properly clean.  The 60X objective lens of the upright microscope does not work properly anymore and I decided not to replace it with a new one since it is extremely expensive.  I decided to switch the optic fiber between inverted and upright. Thus, the shadow will instead appear in the inverted microscope in the cell culture-micro room. We need to place an order for the new optic fiber and I do not know when it will be approved (cost perhaps  >...
