← HistoryWhich image distortion resulted from early microscope lens aberration?
A)Chromatic shift tinging the perimeter✓
B)Vignetting obscuring peripheral light
C)Pin cushion effect magnifying edges
D)Spherical blur reducing central clarity
💡 Explanation
Chromatic aberration plagued early microscopes, because differential refraction introduced color fringing; shorter wavelengths bent more sharply therefore a tinged perimeter appeared, rather than blurred regions typical of spherical aberration caused by uniform lens imperfections.
