  • Patent number: 11717158
    Abstract: A slit lamp microscope of the present invention, which is capable of observing a meibomian gland, comprises: a visible light source for emitting slit light; an infrared light source for emitting infrared light, the infrared light source being disposed on a light path of the slit light emitted from the visible light source; a mirror unit including a reflecting mirror or a prism for reflecting the slit light from the visible light source or the infrared light from the infrared light source to irradiate an eye of a subject; and a switching unit for switching the position of the visible light source and the infrared light source, the switching unit being capable of directing one of the visible light source and the infrared light source toward the light path of the slit light.
    Type: Grant

  • Patent number: 10075628
    Abstract: An imaging apparatus includes a lens, a moving mechanism, an imaging device, and a controller. The moving mechanism moves the lens in the optical axis direction. The controller drives, in response to an input of an imaging instruction, the moving mechanism to move the lens to a plurality of imaging positions from one of infinity and close-up ends to the other and drives the imaging device when the lens is positioned at each of the imaging positions. Since the interior of an oral cavity, for example, is difficult to capture, the focus can hardly be adjusted on it with high accuracy when an autofocus mechanism is used. However, since the lens is moved to the plurality of imaging positions in the optical axis direction in response to each input of the imaging instruction to obtain captured images, an in-focus image can be reliably obtained.
