[Histonet] fluorescent microscope problem
I am having a problem with my fluorescent microscope. It is an old
NIkon Diaphot 300 inverted. I don't expect much from this scope, but
it is usually good enough for a quick evaluation. However, since it
is used by numerous people it is constantly being thrown out of
whack. Today I have encountered a new problem. When I switch to
fluorescence there is a considerable amount of white light coming
through. I can even make out the outline of non-fluorescent cells
when I should only be able to see fluorescence.
Any ideas as to what may be causing this? I have tried everything I
can think of.
