Instrument for measurements in depressions and on concave surfaces The Top View Analyzer – TVA100B is the only instrument in the world to use the top view distance method for measuring the contact angle of a liquid on a solid from above. The innovative measuring method is particularly suitable for measurements in depressions and on concave surfaces where drops cannot be analyzed using the conventional side view. Measuring methods and options ■ Measurements in depressions of well plates ■ Measurement between electronic components on ■ Measuring the contact angle using our top view distance method ■ Special contact angle method for measuring in recesses ■ Surface free energy from contact angles of several test liquids populated boards ■ Measurement on concave optical lenses ■ Surface investigations for the interior of tubes and hoses using all common models ■ Particularly good resolution in the range of small contact angles ■ Easy measurements in patterns such as well plates ■ Available as stand-alone instrument or as a measuring head module for DSA1

Our exclusive top view distance method: how it works With the top view distance method, the curvature of the surface of a drop, which correlates with the contact angle, is determined from the distance of reflected light spots in a video image. These light spots originate from LEDs, which are arranged above the drop. Calculating the contact angle only requires variables which are determined by the setup: the working distance, the distance of the LEDs from one another, the optical enlargement, and the dosed drop volume. Measuring on a concave surface Principle of the top view distance method...
