Advanced Video Contact Angle Measurement System

AST VCA Optima

Product Overview

The VCA Optima is a high-precision video contact angle measurement system designed for surface analysis, adhesion studies, and wettability testing. This system integrates a high-resolution camera, advanced imaging software, and automated analysis tools to provide accurate, repeatable measurements of contact angle, surface energy, and surface tension.

With manual or automatic dispensing, the VCA Optima is an essential tool for quality control, R&D, and material characterization across semiconductor, polymer, coatings, and biomaterials industries. The system offers multiple configurations, including the VCA Optima, VCA Optima S, and VCA Optima XE, with additional features such as dynamic contact angle analysis and motorized syringe control.
