An excellent video, many thanks.

This video has been very useful to me, although I know how and why to use Koehler illumination after quite a time with my microscope. BUT, what this video did 'illuminate' for me was the events that occur with a past microscope of mine, namely the Leitz Orthoplan, which has a light-source (i.e. the bulb and it's filament) that is also able to be moved in the X-Y and the Z relative to the rest of the light train, by use of various turnscrews on the body of the lamphouse. With my later and current Olympus BX 'scope the light-source (again, the bulb and it's filament) is fixed in position within the lamphouse.

Understanding the conjugate planes of both illumination and image-forming is very important if not vital for the correct and optimal alignment of a variey of 'scopes that one may come to use as experience increases.

Thanks for a great link - and to those just starting-out with microscopy - make sure you save this video to your Y-Tube lists - it really is very useful and understandably explained. One of if not the best I've seen.
