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.
