Paper Abstract

This article presents an optical set-up for liquid meniscus planarity measurement at the small capillary tip, which is based on geometric optics principle instead of much more expensive phase shift interference methods. The theoretical study of the meniscus planarity measurement with different geometrical optical set-up is presented. The influence of the set-up alignmen*t errors is also presented. On theses bases has been designed and developed an optical set-up for the measurement of meniscus planarity at the 0,3 mm diameter capillary tip. Necessary radius resolution for the surface tension of liquid measurement was determined and verified the set-up fulfills this condition.
