摘要：
The invention relates to a gas measuring device for the absorption-spectroscopic in-situ determination of at least one chemical and/or physical parameter of a gaseous measurement medium (432), the gas measuring device comprising a first housing (101, 201, 301, 401, 501), at least one laser (102, 202, 302, 402) as a radiation source, which is arranged in the first housing (101, 201, 301, 401, 501), at least one first process window (114, 214, 314, 414, 514) for coupling the radiation emitted by the laser (102, 202, 302, 402) into a measurement medium (432), and at least one detector (103, 203, 303, 403), by means of which the radiation is detected after interaction with the measurement medium (432), characterized in that the first process window (114, 214, 314, 414, 514) is designed as an afocal meniscus lens, which has a convex surface and a concave surface.
