USA KINO invented and used a rotating stage used worm and gear controlled by manual or automatical by motor for the first time in the world. It can be used to measure contact angle of one drop from every direction by rotating this sample stage horizontally with 360°.  It is very useful unit for measurement of contact angle. Because, We found out that contact angle cannot be same from different direction of drop. For example, when we measured contact angle of wafer, due to its coating method, contact angle from one direction is about 15° but if we  rotated wafer about 90° horizontally, contact angle changed to 12°.  And more important thing is for this case we must need to use a calculate method for measuring contact angle of non-axisymmetric drop shape.  Fortunately, USA KINO invented a new method named ADSA-RealDrop. It can used to measure contact angle of non-axisymmetric drop shape.
