COMPACT RAMAN ANALYZER FOR RECORDING DISSOLVED GASES IN LIQUIDS WITH HIGH SENSITIVITY AND SPECTRAL RESOLUTION
摘要
A Raman head is provided capable of operating at high surrounding pressures. The Raman head has housing having a first, sealed chamber filled with an incompressible liquid and a second chamber that is open to the surrounding environment. At least one bellows can be used to equalize pressure between the first sealed chamber and the surrounding environment. A planar side of a pair of plano-concave lens is positioned within the first chamber and the concave side of each plano¬ concave lens is positioned within the second chamber of the Raman head. Light emitted as a result of a laser beam in communication with the pair of plano-concave lens can be analyzed by a Raman analyzer.
