OPTICAL PROBES WITH OPTICAL-CORRECTION COMPONENTS

摘要

PROBLEM TO BE SOLVED: To provide means of correcting the astigmatism, which is generated by the shape of a sheath and reduces the image quality of an optical system.;SOLUTION: An embodiment comprises a sheath 530, a first light-guiding component 501, a second light-guiding component 502, an optical-focusing component 503, and an optical-correction component 507. The second light-guiding component and the optical-focusing component are aligned on an optical axis. The optical-correction component does not directly contact the optical-focusing component, and the optical-correction component is not positioned on the optical axis.;SELECTED DRAWING: Figure 5;COPYRIGHT: (C)2020,JPO&INPIT
