Abstract: A window for use in an adapter for an IR gas analyser for analysing breathing gases, where the gases flow through a through-penetrating passageway in the adapter, which includes windows disposed on opposite sides of the passageway so as to enable an IR beam to be sent through the windows and through the passageway containing said breathing gases. Each window is a one-piece structure comprised of plastic material and has a round basic shape that includes a surrounding edge and a central part which is sunken in relation to the surrounding edge and which forms the window through which the IR beams or rays shall be able to pass. A method of producing such a window, by injection moulding a thermoplastic material in a mould where injection of the plastic material is also disclosed.
