Measuring cell adapted to spectral analysis

A measuring cell for spectro-analytical absorption measurement and spectral analysis of a gas sample contained in said measuring cell and for electric and mechanical co-operation with a carrier, said measuring cell comprising:

• a means for generating light,
• a means for receiving light,
• an inner cavity comprising a number of reflection surfaces thus defining a predetermined, optical measuring path length in the inner cavity of the measuring cell, whereby the inner cavity of the measuring cell is defined by a first part and a second part which co-operate with each other, and
• whereby the first part and/or the second part comprise respective recesses and/or seats, whereby the recesses allow a passage of light beams respectively from the means for generating light and to the means for receiving light,
• whereby the seats entirely or partly hold the means for generating light and/or the means for receiving light,
• whereby the number of reflection surfaces comprises a first reflection surface and a second reflection surface having a concave shape, the first reflection surface reflecting light to the second reflection surface,
• whereby the first part is adapted to rest against said carrier with a first surface facing the carrier being formed with one or two recesses or seats, in order to entirely or partly surround at least said means for generating light, and
• whereby the first reflection surface light is adapted to direct light generated by the means for generating light to a first plane, separated from a second plane in which said means for generating light is located, and that the first part forms a space facing the carrier for the formation of a protected space for electronic components.
