Abstract:
[Problem] To allow imaging light to be appropriately received by a second camera in the case where a first imaging mode (color imaging mode) is changed to a second imaging mode (autofluorescence imaging mode). [Solution] In the first imaging mode, using a dichroic mirror 30 allows light LB to be received by both a first camera C1 and a second camera C2. In the second imaging mode, using a transparent glass 31 allows light LB to be received by the second camera C2. With this configuration, both in the first imaging mode and in the second imaging mode, light LB from an ocular fundus is appropriately received by the second camera C2 whereby an appropriate ocular fundus image can be taken.
