  • Patent number: 7959288
    Abstract: An ophthalmologic imager comprises an illuminating optical system for projecting an illuminating light beam onto an ocular fundus, a light-receiving optical system having a focusing lens and serving to guiding the light reflected from the ocular fundus to an imaging section, and a focusing target projecting optical system having a bar mirror detachably inserted in the optical path of the illuminating optical system and serving to project split focusing target light beams onto the ocular fundus through the bar mirror and the illuminating optical system. A mirror image of the bar mirror is projected onto the ocular fundus by using the illuminating light beam. The ophthalmologic imager further comprises a judging device which judges the sharpness of the contour of the mirror image or the focusing target light imagers from the output of the light-receiving section and judges the focusing state by the focusing lens from the sharpness.

  • Publication number: 20090323023
    Abstract: An ophthalmologic imager comprises an illuminating optical system (10) for projecting an illuminating light beam onto an ocular fundus, a light-receiving optical system (an imaging optical system (20), an observing optical system (30)) having a focusing lens and serving to guiding the light reflected from the ocular fundus to an imaging section (CCD6b), and a focusing target projecting optical system (190) having a bar mirror (190a) detachably inserted in the optical path of the illuminating optical system and serving to project split focusing target light beams onto the ocular fundus through the bar mirror (190a) and the illuminating optical system (10). A mirror image (190a?) of the bar mirror is projected onto the ocular fundus by using the illuminating light beam.

  • Publication number: 20060268230
    Abstract: An ophthalmic apparatus including a photographic optical system (31, 48) capable of photographing a tested eye (E) and obtaining an image of the tested eye, a drive device (76, 83, 90) configured to drive the photographic optical system relative to the tested eye in three-dimensions, an alignment target projecting optical system (56) to project alignment light flux to the tested eye, and a control device (84) configured to control the drive device based on a ate of reflection light flux formed by reflection of the alignment light flux projected by the alignment target projecting optical system on the tested eye, when a flare occurs in the reflection light flux of the alignment light flux reflected on the tested eye, the control device being configured to control the drive device to move the photographic optical system in a direction where the flare decreases.

  • Patent number: 5995282
    Abstract: In an operation microscope, when an observation velocity of an observation field of a main microscope body is set to a desired velocity and then an observation magnification of the observation field of the main microscope body is changed and the focal point thereof is moved, each encoder detects changing of the observation magnification and moving of the focal point and then outputs a detection result to an arithmetic-logic unit. The arithmetic-logic unit calculates the drive condition that a moving velocity of the observation field of the main microscope body after the observation magnification is changed and the focal point is moved is a desired velocity, based on the detection result of each encoder. By using a Y-axis actuator, an X-axis actuator, a vertical direction moving unit and a horizontal direction moving unit, the main microscope body is moved under the control of a CPU in accordance with the drive condition obtained by the arithmetic-logic unit.
