I was trying to use the instructions for the test slide version 2 with the version 1 slide. ( i didn't order what I intended to order)
It works better when you read the label.
Now that I know what I am suppose to be looking for,( and what it looks like when you get it right) my big take away is:
It isn't about finding out how good your microscope is as much as finding out how good YOU can be with your microscope.
I learned that to get the most out of my microscope it has to be fine tuned.
Kohler has to be prefect and with Phase, a slight misalignment will significantly hamper your results.
I also learned that white light vs blue light makes a great deal of difference.
