Abstract

Refractive index is one of the basic physical phenomena of materials. Traditional refractive index measurement has been widely used e.g. In research, in quality inspection of products and raw materials. It is also used for follow up of the different industrial processes. A measuring and research environment, by which it is possible to determine the complex refractive index of liquid samples, was developed in 1996 at the Measuring Instrument laboratory of the University of Oulu. This equipment, based on the reflectance of light measures both the refractive index and absorption factor of liquids simultaneously. While the commercial refractometers are best suitable for research of clear liquids, by the developed equipment it is possible to investigate by the side of clear fluids also dark strongly light absorbing samples. The measuring wave length can be chosen continuously inside the UV-Visual range. The knowing of the wave-length dependence of the complex refractive index gives additional information on the state of the fluid under inspection. The main objective of the task is to solve measuring problems of biotechnology, food industry and forest industry by a new type of refractometric method. This means the simultaneous measurement of refractive index and absorption, and the utilisation of  More>>

The main objective of the task is to solve measuring problems of biotechnology, food industry and forest industry by a new type of refractometric method. This means the simultaneous measurement of refractive index and absorption, and the utilisation of this knowledge in wide spectral region. A refractometer, based on the technology, suitable for applied research of new measuring targets will be designed and constructed in the research. The above mentioned goals also require the survey of the present situation of the refractometry. This one and a half year project will be started in spring 1998. (orig.)}
