近接撮影用装置
Document Type and Number:
Japanese Patent JP7423041
Kind Code:
B2
Abstract:
To provide a close-up imaging device whereby both imaging of an anterior eye and imaging of an eye ground can easily be performed by attaching the device to a mobile terminal such as a smartphone. The above-described problem is solved by a close-up imaging device (1B) detachably mounted to a mobile terminal (9) equipped with a light source (92) and a camera lens (91) for imaging, comprising a color filter member (97) detachably provided above the light source (92), and a convex lens member (93) detachably provided above the camera lens (91). Imaging of an anterior eye is performed by removing the color filter member (97) and attaching the convex lens member (93), and observation of an injury of the anterior eye is performed by attaching the color filter member (97) and the convex lens member (93). The close-up imaging device (1B) may further detachably comprise a slit light forming member that forms light from the light source (92) into slit light by a cylindrical lens, and a tubular member including a convex lens at a tip end thereof.
