Time for another fun microscopy update! If you’re working in a lab and use a microscope occasionally, you may have heard about Köhler illumination. It’s certainly worth knowing about if you want to get the most out of your microscope.



My article  at BitesizeBio will not only help to clue you in to its value, but will take you through the steps to achieve it.

  1. So if this is such a basic step (or seems to be to a non-user), why is it so unknown/uncommon?

    • Sorry, somehow I missed these comments! You know, when most folk start in a lab they’re just “left to it” with a microscope, unless they’re working with someone who’s main work focus involves microscopy (in which case they’d be taught this very early on). There’s a common misconception amongst those who don’t use it a lot that you just have to switch a microscope on and look down it – et voila! Probably because in most cases you’ll see something of your specimen by doing just that. It’s a bit like driving an automatic car – yes you can turn on the engine and make it move, even if it’s your first time in a car and you’re alone – but if you never get someone who drives well to really train you, you’ll never drive well.

  2. That was fascinating—and a lot more complicated than what I did in high school.
