摘要:
The present invention is intended to provide an eye characteristic measuring apparatus having a projection system for projecting a light source image of small amount onto a fundus of an eye by a reflected light from the fundus, and a wavefront detecting system for detecting a wavefront of luminous flux emitted from the interior of the pupil of the eye by a reflected light from the fundus, where the projection system projects a light source image of small amount onto a fundus of an eye, and the wavefront detection system detects the wavefront of luminous flux emitted from the interior of the fundus by a reflected light from the fundus, and a deflection prism having at least one transmission surface for aberration correction within both optical paths of the projecting system and the wavefront detecting system, can deflect the incident luminous flux.
