As a result of the ever increasing demand for automated optical inspection (AOI), Navitar has introduced a line of Easy Reader Auto Focus zoom systems. These systems automatically adjust focus using Digital Signal Processing (DSP) technology.
Navitar's Auto Focus systems are ideal for imaging objects with varying feature heights. The DSP technology used to adjust focus eliminates the need to move the optical system or object to regain sharp focus. This feature can dramatically reduce the cost of developing fixtures.
The Easy Reader Auto Focus systems are RS-232 controllable, allowing computer operation of the camera's zoom, gain, iris, electronic shutter and white balance functions. Navitar
offers Compact Easy Reader AF Systems, High Magnification AF models and many
custom units that can be configured to meet nearly any field of view or
working distance. Please call for more information on configuring an Easy
Reader Auto Focus system to meet your specific needs.
