Abstract
The present invention relates to a device for plasma generation in a wide pressure range. The device comprises a first plasma source () in a first discharge chamber () in order to generate a first plasma in a low-pressure range, a second plasma source () in a second discharge chamber () in order to generate a second plasma in a high-pressure range, a first coupling element () for coupling the device to a system, in order to guide gas out of the system, and a second coupling element () for coupling the device to an optical sensor (). The first discharge chamber () has a first optical connection with at least one optical lens () to the second coupling element () and the second discharge chamber () has a second optical connection with at least one optical lens () to the second coupling element (). This invention further relates to a system for optical gas analysis or gas detection and corresponding methods for plasma generation and for operating the system.
