Abstract: The optical element for surgical microscopes having antifogging properties, antibacterial properties, and durability against autoclave treatment is provided, the optical element including a substrate, an antireflection coating arranged on the substrate, and an antifouling coating layer containing acrylic polymer arranged on the antireflection coating, in which C—H bonding of carbon of the end of the surface of the antifouling coating layer is substituted by C—OSi(OH)3 by a combustion chemical vapor deposition method. A method for production thereof includes steps of coating a solution containing alkoxysilane having an acrylic group on the antireflection coating so as to form the antifouling coating layer, and substituting C—H bonding of carbon of the end of the surface of the antifouling coating layer by C—OSi(OH)3 by a combustion chemical vapor deposition method using silane based gas.

Abstract: The blood flow analysis apparatus includes an acquisition unit and an extractor. The acquisition unit is configured to acquire blood flow information representing time-course changes in a blood flow velocity of a single retinal artery or retinal vein. The extractor is configured to extract one or more parameters corresponding to change in the blood flow velocity from the blood flow information.

Abstract: To provide an ophthalmic device in which an operator can objectively grasp a positional relationship between an eye to be examined and an acquisition optical system, and an operability when the operator controls a position or an orientation of the acquisition optical system can be improved, an ophthalmic device includes an acquisition optical system that acquires eye information of an eye to be examined; an electric position change mechanism that changes a position and an angle change mechanism that changes an orientation of the acquisition optical system with respect to the eye to be examined; a display that is visually recognizable by an operator who operates the electric position change mechanism and the angle change mechanism; and a controller that displays, on the display, positional relationship information indicating a positional relationship between the eye to be examined and the acquisition optical system.

Abstract: An ophthalmic apparatus includes a light source, an iris aperture, a condensing member, a slit, and an image sensor. The light source is positioned substantially conjugate optically to an iris of an eye to be examined. The iris aperture is positioned substantially conjugate optically to the light source. In the iris aperture, an aperture is formed at an eccentric position from an optical axis. Illumination light from the light source passes through the aperture. The condensing member is positioned between the light source and the iris aperture. A slit is positioned substantially conjugate optically to a fundus of the eye to be examined. In the slit, a slit-shaped aperture is formed. The illumination light having passed through the aperture passes through the slit-shaped aperture. The image sensor is configured to receive returning light from the fundus illuminated by the illumination light having passed through the slit.

Abstract: An ophthalmologic apparatus includes a main body including a measurement optical system that measures eye characteristics of a subject eye; an anterior ocular segment camera provided in the main body to acquire an anterior ocular segment image by imaging an anterior ocular segment; and a controller that includes an alignment controller configured to control to adjust a relative positional relationship between the subject eye and the main body based on the anterior ocular segment image. The alignment controller includes an imaging start mode controller that is configured, when it is determined that the subject eye does not appear in the anterior ocular segment image in an imaging start mode by the anterior ocular segment camera, to calculate a predicted position of the subject eye based on image recognition of a face part in the anterior ocular segment image and to control movement toward the calculated predicted position.

Abstract: Provided is an optical interference measuring apparatus including a measuring unit for acquiring an interferogram of an interference wave obtained by irradiating a measuring target and a reference surface with electromagnetic waves and causing reflected waves from a reflecting surface of the measurement target and reflected waves from the reference surface to interfere and a signal processing unit for configuring an intensity profile in the depth direction by performing Fourier transform of the interferogram. The signal processing unit is configured to estimate a parameter for a model formula for an assumed surface count, based on the model formula of an interferogram when it is assumed that the measurement target has a predetermined structure, to select an optimal model by a statistical technique from the model formula to which a parameter estimated for the assumed surface count is applied, and to reconfigure an intensity profile based on the optimal model.
