Abstract: The present invention provides an erythrocyte-culture monitoring device including a light source that radiates monochromatic light onto a culture solution culturing erythrocytes accommodated in a culture container, a first photodetector that detects a light intensity of the monochromatic light transmitted through the culture solution, and a controller that evaluates an amount of hemoglobin in the culture solution based on a temporal change in the light intensity detected by the photodetector.

Abstract: A cell culture apparatus includes: a supply unit that supplies a culture medium to a culture tank accommodating the culture medium and cells; a discharge unit that discharges the culture medium and the cells from the culture tank; and one or more processors comprising hardware, the one or more processors being configured to determine whether or not cell density in the culture medium in the culture tank has exceeded a preliminarily set predetermined threshold, wherein in response to determining that the cell density has exceeded the predetermined threshold, the one or more processors are configured to cause the discharge unit to discharge a portion of the culture medium and the cells from the culture tank and cause the supply unit to supply a new culture medium to the culture tank to reduce the cell density to the predetermined threshold or less.

Abstract: A microscope includes a light source, a condenser lens, an objective lens, a polarizer, a compensator which is disposed on an optical path XA of the light source between the condenser lens and the polarizer and is rotatable about the optical path XA and is configured to adjust variation of retardation with respect to a specimen S by transmitting only a component of light in a specified vibration direction transmitted through the polarizer depending on an angle of rotation from a reference position, a driving unit configured to rotate the compensator, and a control unit configured to cause the compensator to increase or decrease the retardation within a range including a position where the retardation is zero as a reference.
