Abstract
A device comprises a light-guiding component, an optical component, and a light-reflecting component that is configured to receive light from the optical component and direct the light along a path. Also, at least one of the optical component and the light-reflecting component has an optical power in a tangential direction or a sagittal direction that compensates for a negative power of a sheath in the tangential direction to correct for aberration.
