Q: Why are aspheric lenses considered more expensive to manufacture, and in which scenarios are they highly desirable?
A: Aspheric lenses are more expensive to manufacture than spherical lenses due to their complex surface profiles. However, the benefits, including improved image quality, compactness, and lightweight design, make them highly desirable for high-performance optics and situations where a small footprint system is essential, such as in the case of aspheric camera lenses.
