History

Which optical consequence arises when grinding a spherical lens during medieval times resulted in aspherical aberration?

A)Reduced chromatic dispersion at edges
B)Decreased light throughput efficiency
C)Blurred image due to focus deviation
D)Enhanced edge sharpness due to diffraction

💡 Explanation

When lens grinding errors create aspherical aberration, marginal rays focus at different points than paraxial rays due to Snell's Law, leading to a blurred image. Therefore blurred images results, rather than chromatic correction, brightness improvements, diffraction enhancement, which require specific optical designs.
