OCA 50 AF
The&nbsp;automatic video-based optical contact angle&nbsp;and&nbsp;drop contour analysis&nbsp;system OCA 50 AF is the instrument of choice when your application demands for the fully automated, timesaving, set-up and analysis of the&nbsp;homogeneity/wettability of solid surfaces&nbsp;and/or the&nbsp;surface free energy&nbsp;(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 â??push of a buttonâ??.

For bigger samples (e.g. 12â?Â Wafers) the OCA 50 AF L with long X-axis and Y-axis is available.
Features of the base instrument:
 Sample table, software controlled, adjustment in all three axis (X-, Y- and Z-axis). High performance 6x parfocal zoom lens with automated focus and camera tilt angle. Video measuring system with high-resolution USB camera (max. 1220 images/s sample rate). Lighting of the optical path with software controlled intensity adjustment, without hysteresis. Max. sample dimensions (L x W x H):&nbsp; OCA 50 AF: 220 x Ã¤&nbsp;x 70 mm.
&nbsp; Optional OCA accessories: Some of the most important components and accessories are listed below:
 High-speed video system upHSV 3000 (sample rate 3000 images/s). Software controlled electronic multiple dosing systems, E-MDr, for the precise automatic positioning of up to six dosing needles. Direct dosing system, SD-DM, DD-DM, SD-DE or DDE/x. Up to six electronic syringe units, ESr, with precise adjustable dosing speed (0.4 nl/sâ?¦174 Ãµl/s). Electronic tilting base unit, TBU 95, for a maximum tilt angle of 95Ã° and manual tilting base attachment, TBA 60M, for a maximum tilt angle of 70Ã°. Electronic turn table with vacuum fixation, ETTr/VAC, with a wide range of top plates. Temperature and environmental control systems (-30â?¦700 Ã°C). Wide range of sample holding and positioning units. Inc. holders for foils or papers, FSH 30 and FSC 80/150, for single fibres, FHO 40plus, or the suction plate, SP 100, for holding thin flexible samples flat on the stage, with an adjustable suction area. Oscillating drop generators, ODG 20 for the measurement of surface elasticities and for relaxational studies at phase boundaries. Electro-wetting platform, EWP 100, for the analysis of sessile and pendant drops in an electrical field. Top view video system, TV-VS, for the viewing and image capture of the drop position (USB camera with 52 images/s sample rate, 6x parfocal zoom lens and adjustable observation angle). The available software modules for the OCA 50 AF are: SCA 20 â?? contact angle. SCA 21 â?? surface free energy. SCA 22 â?? pendant drop. SCA 23 â?? lamella contour. SCA 26 â?? oscillation / relaxation.
