The latest versions of the LE AF USB 3.1 Gen 1 board-level cameras with liquid lenses from IDS now include single-shot autofocus capability. The liquid lenses enable the switching of focus in milliseconds for different object distances. These lenses operate for millions of cycles, are wear-free and have no moving parts, making them particularly suitable for applications where the working distance changes frequently and reliability is important.
Application examples include: logistics systems (such as for parcel receipt and sorting), rapid focusing in microscopy, traffic monitoring, and small medical or industrial devices.
The uEye LE AF liquid lens can be manually focused through software, using either the uEye Cockpit user interface or API. This not only provides precise control over focusing but is also especially useful in applications such as traffic monitoring where the lens cannot be reached manually. Autofocus is now also possible with these lenses thanks to the release of IDS Software Suite 4.92.
The single shot autofocus can be easily triggered via software. It can be individually configured according to the requirements of different applications and ensures sharp images in the blink of an eye. As always, the IDS Software Suite release is backward-compatible, so existing users of the uEye LE AF with just active focus capability can upgrade to include the autofocus function.
Users can choose between models with the 6.4MP IMX178 rolling shutter sensor from Sony or the high-resolution 18.1MP AR1820HS rolling shutter sensor from ON Semiconductor. Further sensors will follow. All models are equipped with a 10-pin, lockable I/O Molex connector for GPIO, trigger and flash, and enable IDS-typical plug-and-play functionality. USB Power Delivery enables variable power to be supplied for peripheral devices at the I/O port. Follow the link for full details of the models available.
Housings for the cameras can be created using 3D printing. The 3D print data for both active focus and autofocus versions of the uEye LE USB 3.1. Gen 1 series are available as STL files.
A new techtip Automatically in focus is available and explains how the autofocus system works.
