OCA 50 & 50EC

Optical Contact Angle – OCA 50 & OCA 50EC

The 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 positions 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 access to 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 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.
