Patent ID: 7219999

Claim:
A device for measuring an optical characteristic of an eye, comprising: a first light source for emitting a luminous flux of a first wavelength; a first illumination optical system for performing illumination by a first illumination luminous flux which is from the first light source and is converged to a vicinity of a center of a fundus of an eye to be examined; a second light source for emitting a luminous flux of a second wavelength; a second illumination optical system for illuminating an observation area of the fundus of the eye to be examined by a second illumination luminous flux from the second light source; a beam splitter for branching a reflected luminous flux reflected from the fundus of the eye to be examined into a first branch luminous flux containing most of the reflected luminous flux of the first wavelength and a second branch luminous flux containing a remaining portion of the reflected luminous flux of the first wavelength and the reflected luminous flux of the second wavelength; a first reception optical system for receiving the first branch luminous flux branched by the beam splitter and for guiding the first branch luminous flux so as to be received through a first conversion member for converting it into at least 17 beams; a first light receiving part for receiving the first branch luminous flux from the first reception optical system; a second reception optical system for guiding the second branch luminous flux branched by the beam splitter so as to be received; a second light receiving part for receiving the second branch luminous flux from the second reception optical system; an arithmetic part for obtaining the optical characteristic of the eye to be examined on the basis of an inclination angle of the luminous flux obtained by the first light receiving part; and a display part for enabling confirmation of an irradiation position of the first illumination luminous flux on the fundus by a signal from the second light receiving part.
