Which Lens Material Requires the Most Effort to Craft?

[stunner5000pt]

If you had to choose between ice(n=1.31), glass (n=1.52), or diamond(n=2.42) which would be the hardest lens to make? Which woukl be the easiest lens to make??

the one with the least radius of curvature would need the most work done on it because of the small value needed. On the other hand if the radius of curvature is large it would be relatively easy to make because of lesser wiork needed to make this lens.

we're talking about making a thin symmetric convex lens here whoe focla length would be 10 cm in all cases.

is this right? is this how this should be understood??

Yes, this is correct. The diamond would be the hardest lens to make as it has the highest refractive index, and the ice lens would be the easiest to make as it has the lowest refractive index.

Yes, your understanding is correct. The lens with the smallest radius of curvature would require more precision and effort to make compared to a lens with a larger radius of curvature. Therefore, the diamond lens (n=2.42) would be the hardest to make, while the glass lens (n=1.52) would be the easiest to make. This is because diamond has a higher refractive index and a smaller radius of curvature compared to glass, making it more difficult to shape and polish.
