No idea how that particular software or microscope works, but if it connects via ethernet there shouldn't be any problem, as long as the microscope is attached to the network (router) or directly and you are connected to the same network (LAN) with an IP address in the same subnet for both (for instance: 192.168.x.x), it should be like exactly like using a PC with Windows.
If you connect a cable directly from the ethernet port of the Mac or PC to the microscope there is no DHCP server in the middle giving out IP addresses and thus both will use self-assigned IPs which is probably why it isn't working.
Again, once the Virtual Machine is in Bridge mode, in this case there is absolutely no difference from a PC and you should follow the User Guide of the microscope as you would for a PC.
