Marcin, of course, the position of the light source - in other words:
the light path - is also important. You can use this bulb in your picture
when you look at a meteorite (slice) in reflected light. In that case the
light is directed onto the - usually flat - surface of your meteorite sample.

But, when studying or photographing thin sections, you examine your samples in
transmitted or in cross-polarized light. In that case, the light passes up through
your thin section from below - that's where your (sub-) stage glass is broken in
the photo of your microscope. This rectangular opening one can see right under
the broken glass plate, ... that's where the light must come from when you look
at a TS in transmitted or in polarized light.

Best wishes,

Bernd
