Solution
Correct Answer:
Sum of individual powers
When several thin lenses are placed in contact, the effective power (P) of the combination is the algebraic sum of the individual powers: P=P1+P2+P3+... This implies for focal lengths: F1=f11+f21+...
- This arrangement increases the field of view and reduces aberrations.
