Intrinsically Safe Optical Spectrum Analyzers

Abstract

A laser spectrometer is operable to analyze one or more analytes present in a combustible gas mixture. The spectrometer can include one or more features that enable intrinsically safe operation. That is, electrical, electronic and, thermal and / or optical energy sources can be restricted in hazardous areas of the spectrometer where explosive gas mixtures may be present.

Background technique [0004] In electronic equipment located in atmospheres where explosive or other combustion hazards may exist, it is desirable to eliminate these hazards. Presently practical methods include making all enclosures and connections resistant to hazardous atmosphere explosions. However, doing so can be expensive and requires adding bulky and inconvenient components and structures to the instrument. In particular, explosion-proof enclosures that ...

However, doing so can be expensive and requires adding bulky and inconvenient components and structures to the instrument

In particular, explosion-proof enclosures that include optical windows of very high quality to pass through the delicate laser beams can be rather difficult to design and expensive to manufacture
