| 摘要 |
Method for measuring a chemical composition of a sample comprising at least two chemical components, comprises the steps: illuminating an integrating cavity by a light source, bringing the sample into the integrating cavity, detecting an optical signal from the integrating cavity using a sensor, and indicating the chemical composition of the sample by spectral analysis. The sample forms an optically thin layer in at least one dimension inside the integrating cavity. The patent application contains independent patent claims also for optical measuring apparatus and method for measuring a chemical composition of a sample. |
