Abstract: In order to provide a more practical gas analysis device than that having conventionally been, while keeping the laser source and the photodetector separated from the gas cell, thereby preventing exposure to a high temperature, the gas analysis device includes: a gas cell; a laser source or a photodetector separated from the gas cell; and a laser light transmission mechanism provided between the gas cell and the laser source or the photodetector. The laser light transmission mechanism includes one or a plurality of tubular members, and an inner space of the one or the plurality of tubular members provides a light path for the laser light.

Abstract: The present invention reduces thermal stress that is generated in a join portion of a window material in an optical measurement cell, and is an optical measurement cell having translucent windows through which light is transmitted and into an interior of which is introduced a test sample. This optical measurement cell has a planar window material that forms the translucent windows, a join supporting portion that is joined to an outer edge portion of a main surface of the window material and supports the window material, and a low thermal expansion component that is provided on an outer-side circumferential surface of the join supporting portion and whose coefficient of thermal expansion is lower than a coefficient of thermal expansion of the join supporting portion.

Abstract: A gas analyzing device that irradiates a gas with a laser beam and detects the laser beam having penetrated the gas to analyze a component to be measured contained in the gas is configured so as to reduce a moment in a gravity direction generated about a fulcrum of an attachment location or the like is reduced to suppress optical deviation as much as possible. The gas analyzing device includes a gas cell attached to a piping through which the gas flows and into which the gas is introduced, and an elongated optical cell connected to the gas cell from a predetermined connection direction. The optical cell accommodates an optical system supported by a surface plate in a state of being disposed on an optical path of the laser beam. The optical cell stands up with respect to the connection direction.
