The Goniometer II can be used for geometry measurement, as well as the precision measurement of refractive indices of transparent media in the UV-VIS-IR from 254nm – 2325nm. Refractive index measurements are accurate to 1 in the 5th decimal place. Liquids can be measured using a special hollow prism.
While the Goniometer II is outdated by the GONIOMAT series, it is still an excellent instrument for certain applications.
