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.
A window for use in an adapter (3) for an IR gas analyser for the analysis of respiratory gases, where the gases flow through a through-penetrating passageway (9) in the adapter (3) with a window (8) disposed on mutually opposite sides of the passageway (9) so that an IR beam can be sent through the windows (8) and the passageway (9) containing said breathing gases, wherein the window (8) is a one-piece structure made of plastic material and having a round basic shape that includes a surrounding edge (8″) and a central part (8′) which is sunken in relation to said edge (8″) and which constitutes the window through which the IR rays shall be able to pass, and a center part of the window (8) generally lies flush with an inner wall surface (7′).
