A good camera lens contains optical components in which two pieces of glass are glued directly together to form a single transparent object. These two-element optical components are important because they
A) bend light more efficiently than simple lenses.
B) reflect less light than simple lenses.
C) have larger depths of focus than simple lenses.
D) avoid the color focusing problems of simple lenses.

Question

Quizplus · Accepted Answer

Two-element optical components, or achromatic lenses, are designed to correct chromatic aberration, which is a type of distortion where a lens fails to focus all colors to the same convergence point. This results in color fringing or blurring, a problem that simple lenses often have. By combining glasses with different refractive indices, these components minimize the issue, leading to clearer and more accurate color representation in the images captured.
