Spherical aberration distorts images generated with a light microscope. In this Microcourse, you'll learn what spherical aberration is, what is does to your images, where it comes from and how to deal with it.
Thanks to my fabulous group for feedback on this video prior to release: Talley Lambert, Anna Jost, Rylie Walsh & Federico Gasparoli.
