Optical contact angle measuring- OCA 200

OCA 200 – Precision Optical Contact Angle Measuring for Advanced Surface Analysis

The OCA 200 from DataPhysics Instruments is a cutting-edge optical contact angle measuring instrument engineered for both micro and macro surface characterization. Designed to support the most demanding research and quality control tasks, the OCA 200 delivers unparalleled accuracy in drop shape analysis and surface energy evaluation.

Equipped with a motorized sample stage that moves in X, Y, and Z directions, the oca 200 ensures precise sample positioning for repeatable measurements. The integrated 10x zoom lens with autofocus allows for sharp imaging across a wide range of sample sizes—from large wafers to microscopic wires—making it suitable for both industrial and biomedical applications.

A USB 3.0 high-speed camera captures high-resolution images and videos for detailed dynamic and static contact angle analysis. Complemented by a software-controlled LED illumination system, the OCA 200 ensures consistent lighting with temperature drift compensation for stable image quality.

This instrument supports advanced dosing systems, including nanolitre and picolitre dispensers, enabling contact angle measurement on even the smallest sample surfaces, such as stent wires or implant threads. A touchscreen control panel offers intuitive navigation and control, enhancing user experience and operational efficiency.

The OCA 200 is ideal for evaluating wettability, adhesion, interfacial tension, and surface free energy in applications ranging from materials research to pharmaceuticals and coatings.

With its modular upgrade options—such as environmental chambers, tilting base units, and advanced imaging tools—the OCA 200 adapts seamlessly to evolving testing needs, making it a future-ready investment in precision surface science.

The Optical contact angle measuring- OCA 200 is the contact angle measuring and drop contour analysis system for microscopic and macroscopic structures. The software-controlled, electrically driven optic alignment enables the OCA 200 to adjust the observation angle and to focus automatically. With the trendsetting 10-fold zoom lens and the reliable auto focus system by DataPhysics Instruments, the OCA 200 is equipped to handle any kind of sample size from a macroscopic silicon wafer to the microscopic mesh structure of a coronary stent. In combination with the high-performance camera with USB 3 interface even smallest drops of highly volatile liquids can be monitored.

The electrically driven sample table makes it possible to position micro-structured samples with highest precision and exceptional speed for fast automated measuring procedures. With an electronic multiple direct dosing system DDE/x and up to four electronic syringe modules ESr-N liquids can be deposited on a macroscopic sample and its surface parameters can be determined automatically.
