Newton thought it was impossible to eliminate, but Euler presented the macula lutea as an example of a system that counteracts it.
Newton thought it was impossible to eliminate, but Euler presented the macula lutea as an example of a system that counteracts it. Chester Moor Hall's invention of a crown and flint system – later patented by John Dollond after a legal struggle – proved that not all glass had the same index of refraction, as Newton argued, and that putting a concave lens after a standard lens would allow different wavelengths to experience the same amount of refraction. For ten points, identify this type of aberration where different colors have different focal points.
