| 摘要 |
The invention relates to a reimaging optical system that has a sufficiently enhanced magnification and better performance, and an endoscope using the same. The reimaging optical system 3 is adapted to re-form an image by an image guide 6 on a solid-state imaging device 4 having a diagonal length of 6.5 mm or longer, and satisfies the following condition. <?in-line-formulae description="In-line Formulae" end="lead"?>0.6<(Dxbeta)/V (1)<?in-line-formulae description="In-line Formulae" end="tail"?> Here D is the diameter of the image guide 6, beta is the optical transverse magnification of the reimaging optical system 3, and V in mm is the minor axis direction length of an imaging area of the solid-state imaging device 4.
