Abstract
An optical probe comprises a light-guiding component, an optical component, a light-reflecting component that is configured to receive light from the optical component and direct the light along a path, and a correction component. The correction component lies in the path, the correction component has an optical power, and the correction component has a center of curvature that substantially coincides with an optical axis of the optical component.
