Question about Science & Laboratory
You should start by changing the bulb, even though it looks ok chances are that it's no longer working. Do the same with the fuse if the new bulb doesn't work.
Test that power is reaching the socket with a voltmeter or a multimeter so ensure the wiring is ok with the new fuse. If no power is reaching the bulb socket, then you will need to check the wiring every step of the way.

You can purchase a variable power supply that will light this lamp and control its intensity if you determine that the power supply in the microscope is bad. This may be the easiest way to fix the problem. Parts for many older microscopes are no longer available and this is a common way to repair the microscope. It's also a common modification made to many laboratory instruments for research purposes. Carefully check the lampsocket as well. It's common for them to fail and replacement is the only cure. The lamp socket is not expensive.
