Process Control

Development of optical technologies and optical devices with higher and higher requirements and tougher parameters from the one hand and the focus on mass market with huge volume and sencitivity to cost and yield demand new level of coating process control.

For any evaporation process accurate deposition rate and thickness control is essential. IZOVAC designed multy crystals heads (chamger unite) with fast chaging of crystals. It is included in a basic configuration of any ORTUS coater and together with quartz monor allows to get stable deposition rate and refractive index for optical coatings.

For precision optical interferrence coatings that consists of tens of layers together with stable refractive index and deposition rate need a tool that control directly optical parameters of filter. The tool which can automatically detect the stop point of every layer with high precision in order to get required spec of final filter. And the tool which can analize mistakes in previouce layers and automaticaly correct next one for compensation.
IZOVAC developed Optical Coater Provider (OCP) to obtain sophisticated multilayer optical staks on any kind of PVD or PECVD coating equipment.
Having multiple options and working mode as Broad Band (spectral) and Single Wave control, Transmition and Reflection mode, Stationary and Fying witness OCP is aimed to transform standart coater to efective high precision tool that satisfy next generation requirements.

Intellectual real-time optimization function controls the current result of coating and in case of deviation from the required one it recalculates and makes correction for next layers to ensure that final optical coating has exacte properties that you intended.
