Cognex提供了最先进的技术，可用于1-D条形码和2-D数据矩阵代码读取。
One of the keys to any machine vision or barcode reading application is selecting the right lens. There are a few important considerations including field of view, aperture, sensor compatibility, and focal point. Traditional optics have mechanical parts that require an operator to set at a fixed focal point. Once set, the focal point is very difficult to adjust if the distance to the target suddenly changes.
自动对焦技术通过与人眼相同的方式工作，重塑和弯曲，以解决这个问题，以便在没有任何机械零件的情况下进行聚焦。这种重新集中的还可以通过软件来完成，从而消除了操作员手动调整现场或线路上的镜头的需求。
With the latest high-speed liquid lens (HSLL) technology from Cognex, users are able to achieve easy setup and dynamic autofocusing in presentation reading as well as high-speed, high-variability applications. Setup requires only one click in the software to focus the camera. And, as the distance from the object to the camera changes, the lens automatically adjusts the focus frame by frame.
The benefits of HSLL include:- No mechanical parts or manual intervention needed
- Fewer cameras needed for applications requiring large depth-of-field
- 2至3毫秒重新聚焦，每次确保清晰的图像
