VERFAHREN UND VORRICHTUNG ZUR UNTERSUCHUNG VON GASEN ODER GASGEMISCHEN MITTELS LASERDIODENSPEKTROSKOPIE

In a process to determine the concentration of gas within a lamp, the lamp is located between two parabolic mirrors of different radius and focused on the lamp. A laser beam is directed at a first parabolic mirror and then follows an increasingly divergent path as it is reflected back and forth betw...

description	In a process to determine the concentration of gas within a lamp, the lamp is located between two parabolic mirrors of different radius and focused on the lamp. A laser beam is directed at a first parabolic mirror and then follows an increasingly divergent path as it is reflected back and forth between the mirrors through the lamp. An independent claim is included for an assembly for use in the above process, incorporating one or more laser diode light sources or narrow frequency (0.6 mu m to 2.5 mu m) bandwidth following the longest possible route prior to measurement with a spectrometer. The laser beam impinges on the lamp at right angles or as close to right angles as possible. The parabolic mirrors have a copper or gold reflective surface.
