How to install a photographic system on a microscope? Which company can provide the camera system? Can Olympus provide it?

This needs professional equipment, and Olympus can do it. This equipment should be called microscope photography system.

I looked it up on purpose.

Ordinary microscopes need to be equipped with a microscope camera and a digital microscope interface. If it is a three-eye microscope, you can use the standard C interface on the third eyepiece to directly connect with the C interface of the microscope camera (the microscope camera produced by general manufacturers is a standard C interface). Of course, after adding the camera, you need to add a computer, which is to transform the ordinary microscope into a cost-effective digital microscope.
