OCP Singlewave Monochromatic system

The high speed digitizing of the measured data allows to obtain a stable signal even at minimum measurement times, which makes it possible to monitor the process in equipment with high-speed linear motion of the test glass. The operation with baseline signal calibration avoids any signal changes, not directly connected with the film deposition process on the surface of the object under control. The developed mathematical algorithm allows to approximate measured data with at worst insignificant errors. That makes it possible to find  the stop layer point with a hundred percent accuracy and send a stop layer signal to the vacuum equipment control. This precision allows to carry out deposition process from the beginning to the end automatically. A wide range of options allow you to configure OCP Singlewave to satisfy all the requirements of the process are working on.

The OCP supports the most popular softwares for optical design creation as Essential Macleod, OptiLayer, TFCalc as well as MS Excel and MS Text files. The created optical design is uploaded to the OCP where it is possible to see the coating structure layer by layer. The user friendly interface of OCP software provides all visual information in order to operate the process in automatic or in manual mode.
