Document Type and Number:
Japanese Patent JP6710839
Kind Code:
B2
Abstract:
This measurement cell is provided with: a housing (31a) which comprises multiple optical paths (33a-33r) that guide light towards a circular opening (35) and multiple second optical paths (34a-34r) that are provided corresponding to the first optical paths and receive light from the opening; a window member (44) which is ring-shape, translucent, and arranged along the opening; and a ring-shape holding member (42) which holds the window member. The window member (44) is configured from multiple arcuate members (44a-44d).
