| 发明名称 | Gas analyser | ||
| 摘要 | A gas analyzer for the absorption-spectroscopic in-situ determination of at least one chemical and/or physical parameter of a gaseous measurement medium, wherein the gas analyzer includes a first housing; at least one laser as a radiation source, which laser is arranged in the first housing; at least one first process window for coupling the radiation emitted by the laser into a measurement medium; and at least one detector by which, following interaction with the measurement medium, the radiation is detected. The first process window can be configured as an afocal meniscus lens having a convex surface and a concave surface. | ||

| 主权项 | 1. A gas analyser for absorption-spectroscopic in-situ determination of at least one chemical and/or physical parameter of a gaseous measurement medium, wherein the gas analyser comprises: a first housing; at least one laser as a radiation source, which laser is arranged in the first housing; at least one first process window for coupling radiation emitted by the laser into a measurement medium; and at least one detector configured to detect radiation following interaction with the measurement medium wherein the first process window is configured as an afocal meniscus lens having a body, the body having a convex surface and a concave surface opposite the convex surface. | ||
