Aberrations fall into two classes: monochromatic and chromatic.
Monochromatic aberrations are caused by the geometry of the lens or mirror and occur both when light is reflected and when it is refracted. They appear even when using monochromatic light, hence the name.
Chromatic aberrations on the other hand are caused by dispersion, because of this dispersion, different wavelengths of light come to focus at different points. Chromatic aberrations do not occur when monochromatic light is used.
Well, a few days ago we had a chromatic aberration above, and today we have a monochromatic one below!
Not really, but why have one aberration when you can have two!

Thanks and sorry John. I should have said a light “aberration” is when the light is bent (reflected or refracted) making it appear different or in a different location. A bit like when a star appears to be in a different spot because its light is bent by the earth’s atmosphere. My “aberration” models are “aberrations” of their previous self and have nothing to do with light so I should have shut up!
SORRY!

Haha, thanks for the explanation, Dave! 🙂 Of course, you can never rule out that I’m a bit thick! 😉

Wargamers are never thick, accept around the waste. Obtuse, vague, and bad dice rollers with a weird sense of humour, maybe, but never thick.

Thanks Faust . The twins are progressing nicely. They are looking across at the painting table and noticing lunch being lovingly painted for them!
