Which phenomenon limited the angular expansion observable through early microscope designs (c. 1600s)?

💡 Explanation

Spherical aberration arises because lenses focus rays non-uniformly depending on their distance from the optical axis. This prevents the image from forming a perfect focal point, therefore blurring the view rather than chromatic defects which relates to color.
