How to pronounce “spherical aberration” in English

This is called spherical aberration.

This is called spherical aberration, and it distorts every radially symmetric magnetic lens.

the presence of spherical aberration will always be in the way.

But there is a surprisingly simple way to minimize spherical aberration.

Now, a diverging lens also suffers from spherical aberration.

So if they got their maths and engineering exactly right, they could feed an image with spherical aberration through these two lenses to almost completely counteract the effect.

These were easier to build, and because they didn't use any lenses, they weren't limited by spherical aberration.

And maybe, just maybe, this small part could correct the spherical aberration of the original lens.

But now they, calculated this new image might have the remnants of that tiny divergence still in its center, with spherical aberration pointing in the opposite way.
