Abstract: An observation system includes an illumination unit including a light source from which emits an illumination light including light of a plurality of colors, and light receiving unit including an optical sensor which acquires a light intensity. The illumination unit emits the illumination light for a culture vessel so that the illumination light travels from a first side to a second side of the culture vessel, the first side and the second side being defined by interposing a culture medium. The light receiving unit receives, on the first side, light emitted from the illumination unit, entering the culture vessel from the first side, reflected at the second side, and transmitted through the culture medium, and acquires a light intensity for each color in the received light for calculation of a pH value of the culture medium.

Abstract: An observation system includes an observation apparatus including a housing having an arrangement surface for placement of a sample, the sample including a culture medium, and an external illumination unit which is disposed outside the housing and includes at least one light source configured to emit illumination light. At least a part of the arrangement surface is formed of a transparent member having an optically transparent property. The observation apparatus includes an imaging unit which is provided in the housing and includes an image sensor configured to image, via the transparent member, the sample illuminated by the illumination light from the external illumination unit to acquire images of at least three colors.

Abstract: An observation apparatus includes: an image capturing apparatus that includes an imaging surface and captures an image of an object to be observed; an optical system that projects an optical image of the object onto the image capturing apparatus; a focusing unit that adjusts, with reference to the optical-axis direction of the optical system, the relative positional relationship between the object and a surface optically conjugate to the imaging surface; and a processor that controls at least the image capturing apparatus and the focusing unit. The processor decides an in-focus position for the focusing unit based on a plurality of images of the object that acquired by the image capturing apparatus, the plurality of images each being an image acquired when the focusing unit is located at a different position; determines the reliability of the decided in-focus position; and when determining that the in-focus position is not reliable, moves the focusing unit sequentially to a plurality of positions and causes the image capturing apparatus to acquire, for each of the plurality of positions, a candidate image of the object.

Abstract: This cooling mechanism for a surface-mounted-type photoelectric conversion element is provided on a circuit board to which a surface-mounted-type photoelectric conversion element, which has a signal terminal that is connected to inner wiring and a terminal for fixation that is not connected to the inner wiring on a back surface thereof, is mounted, the cooling mechanism has a front-surface-side copper foil pattern to which the terminal for fixation is connected, a back-surface-side copper foil pattern, and a through-hole via which connects the copper foil patterns, a cooling member which is fixed to the circuit board so as to have contact with the back-surface-side copper foil pattern, and which cools the back-surface-side copper foil pattern.
