The<b>&nbsp;automatic video-based optical contact angle</b>&nbsp;and&nbsp;<b>drop contour analysis</b>&nbsp;system OCA 50 is the instrument of choice when your application demands for the fully automated, timesaving, set-up and analysis of the&nbsp;<b>homogeneity/wettability of solid surfaces&nbsp;</b>and/or the<b>&nbsp;surface free energy&nbsp;</b>(inc. polar/disperse components) of solids. The automated sequence of tests and the video-based optical image processing facilitates the analysis of simple and complex sample structures at the ‘push of a button’.

For bigger samples (e.g. 12” Wafers) the OCA 50 L with long X-axis and Y-axis is available.
<b>Features of the base instrument:</b>
<ul><li>Sample table, software controlled, adjustment in all three axis (X-, Y- and Z-axis).</li><li>High performance 6x parfocal zoom lens with integrated continuous fine focus, and adjustable observation and camera tilt angle.</li><li>Video measuring system with high-resolution USB camera (max. 123 images/s sample rate).</li><li>Lighting of the optical path with software controlled intensity adjustment, without hysteresis.</li><li>Max. sample dimensions (L x W x H):&nbsp;<br /><strong>OCA 50</strong>: 220 x ¤ x 70 mm.</li></ul>
&nbsp;<br /><b>Optional OCA accessories:<br /></b>Some of the most important components and accessories are listed below:
