The application "Free-surface
goniometry" was developed by FEMTOFAB for the first time in the world!
>> What is free-surface goniometry?
It is the calculation method of contact
angles only by FEMTOFAB where the free surface (without distortion) is measured
excluding the surfaces of liquid droplet with interface distortion and optical
distortion to obtain accurate values by reversely calculating the distorted
contact surface.

in the world
- GEM engine is applied where gravity-driven deformation of interfaces is
accurately analyzed numerically.
- Contact angle is measured using only free-surface domains without any distortion.
- The most ideal measurement of contact angles completely excluding fundamental
distortions (interface distortion, optical distortion) near the contact line.
* With existing approximate algorithms, errors greater than 10° occurs

* With existing approximate algorithms, errors greater than 10° occurs
in superhydrophobic domains.
* Single algorithm measurement for the whole domain: All of accuracy, repeatability,
convenience maximized because there is no need for selection of an algorithm.
