Optical contact angle measuring- OCA 50

OCA 50 – Fully Automated Optical Contact Angle Measuring for Precision Surface Analysis

The OCA 50 from DataPhysics Instruments is a high-performance optical contact angle measuring instrument designed for accurate drop shape analysis and surface energy evaluation. Its fully automated design makes it an essential tool for research laboratories, academic institutions, and industrial quality control settings requiring precise and repeatable surface measurements.

With a motorized sample stage controllable in X, Y, and Z axes, the oca 50  offers high positioning accuracy for various sample types. The integrated 6.5x zoom lens with continuous fine focus and adjustable viewing angle ensures crisp and accurate imaging for both micro and macro surfaces. The powerful USB 3.0 camera captures static and dynamic contact angles at high resolution and frame rates, supporting detailed wetting behavior studies.

The LED illumination system, adjustable both manually and via software, provides stable and uniform lighting with temperature drift compensation for consistent results. A user-friendly TP 50 touchscreen control panel enhances operational efficiency, offering precision control over the system’s advanced features.

The OCA 50 supports multiple dosing modules, including nanolitre and picolitre dispensers, making it capable of handling ultra-small droplets for advanced material surface analysis. Optional accessories like environmental chambers and tilting stages expand its capabilities for more complex testing environments.

Whether you’re measuring surface wettability, adhesion, or interfacial tension, the oca 50  delivers high-accuracy data for confident decision-making in both R&D and production settings.

The Optical contact angle measuring- OCA 50 is the fully automatic measuring device for the time-saving analysis of the wettability of solid surfaces and the determination of the surface energy of solids. The sample table of the OCA 50 can be positioned along all three directions in space via electronic high-performance axes, with both extraordinary speed and highest precision. Combined with an electronic multiple direct dosing system DDE/x and up to four electronic syringe modules ESr-N the determination of surface parameters can be automated completely. The automation of measurements succeeds easier than ever before thanks to the intuitive automation dialogue of the OCA software and its visual drop positioning system. Hence it is possible to determine, for example, the surface energy with four test liquids at different position of even large samples without any manual user intervention. This facilitates a complete and automated sample mapping.

In order to map silicon wafers, electronic turn tables with vacuum fixation are available. They allow to access any position for contact angle measurements, even on 12″ wafers. In any case, the 6.5-fold zoom lens and the high-performance camera with USB 3 interface ensure optimal images of the deposited drops. For a fast and intuitive device control, even during complex measurements, the TP 50 control panel with touch screen and precision control wheel is included with every OCA 50.
