Department of Optoelectronics and Electronic Systems, Gdansk University of Technology, ul. Narutowicza 11/12, 80-952 Gdansk, Poland
A high resolution optical refractometer for dispersion measurement in the UV-NIR range is described. Using this refractometer, refractive index of a range of liquid samples, such as aqueous solutions of sugars, salts and alcohols, was measured as a function of wavelength in the range from 300 nm to 920 nm with accuracy better than 10 - 5. So accurate results can be used for improvement of resolution of OCT measurements conducted in biological samples.
