装置。A device that holds a rectangular parallelepiped-shaped beam splitter in which two right-angled prisms are brought into contact with each other on their slopes, and the abutting surfaces are provided with a light separation function, and has a square hole into which the beam splitter is loosely fitted. , a hole for an optical path is formed, and two adjacent surfaces of the inner wall of the square hole are formed as a reference plane so that they are perpendicular to the optical axis of each split light to be separated by the beam splitter. A beam splitter that is loosely fitted into the square hole of the holding member, and pressing and fixing means that presses and fixes the beam splitter loosely fitted into the square hole of the holding member against the two reference surfaces. Splitter holding device.
