Abstract: A fundus camera for reliably performing fundus imaging in a state where no miosis has been caused in the pupil of a subject eye, and a corresponding method. The fundus camera includes a camera main body configured to image the fundus of a subject eye, an anterior ocular segment image acquiring unit configured to repeatedly acquire an anterior ocular segment image of the subject eye at least before the imaging of the fundus by the camera main body, a pupil diameter detecting unit configured to repeatedly detect the pupil diameter of the subject eye based on the anterior ocular segment image repeatedly acquired by the anterior ocular segment image acquiring unit, and an imaging control unit configured to cause the camera main body to image the fundus in a case where the pupil diameter detected by the pupil diameter detecting unit reaches a predetermined first threshold value or more.

Abstract: An OCT apparatus of an exemplary aspect includes an OCT scanner, image data generating unit, registration unit, and image data composing unit. The OCT scanner is configured to acquire three dimensional data sets by applying an OCT scan to mutually different three dimensional regions of a sample. The image data generating unit is configured to generate a plurality of pieces of image data from the three dimensional data sets. The registration unit is configured to perform a first registration between the plurality of pieces of image data by applying an image correlation calculation to each of overlap regions in the plurality of pieces of image data. The image data composing unit is configured to compose the plurality of pieces of image data based on a result of the first registration.

Abstract: A slit lamp microscope of an aspect example includes an illumination system, first photographing system, fixation system, movement mechanism, and controller. The illumination system projects slit light onto an anterior segment of a subject's eye from a first direction. The first photographing system photographs the anterior segment onto which the slit light is being projected, from a second direction different from the first direction. The fixation system outputs fixation light for fixation of the subject's eye. The movement mechanism moves the illumination system and the first photographing system. the controller performs a first control for the movement mechanism to move at least the illumination system and a second control for the first photographing system to photograph the anterior segment a plurality of times in parallel with each other while causing the fixation system to output the fixation light.

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.
