Question

3. Coma can be corrected by using corrective lenses placed symmetrically around the axis.

please give me answer quickly ..​

Answer 1

Answer:

For a single lens, coma can be partially corrected by bending the lens. More complete correction can be achieved by using a combination of lenses symmetric about a central stop. Coma is shape-dependent, so a lens shape can be found with zero coma for a given object distance.
