| 摘要 |
An ophthalmic photographic device includes an illumination optical system for irradiating a fundus oculi of an eye to be examined with illuminating light, a photographic optical system to photograph fundus oculi, an indicator projecting optical system for projecting an indicator on the fundus oculi, and a focusing detection optical system which has a photoelectric converter receiving light of the indicator projected on the fundus oculi and detects focus information based on an output from the photoelectric converter. According to the present invention, the ophthalmic photographic device further includes a barrier filter for fluorescent photography which is used in fluorescent photography to cut off exciting light and to transmit fluorescent light from the fundus oculi and light having longer wavelengths than the fluorescent light over a predetermined wavelength range, and a barrier filter for infrared fluorescent photography which is used in infrared fluorescent photography to cut off exciting light and to transmit infrared fluorescent light from the fundus oculi and light having longer wavelengths than the infrared fluorescent light over a predetermined wavelength range. The barrier filters are adapted to be selectively used according to photographic conditions.
