Liquid lens optics for DataMan 300

Share this on social media:

Cognex has added liquid lens optics for the DataMan 300 series of fixed-mount barcode readers. The new accessory allows any DataMan 300 reader to be easily upgraded from fixed focus to autofocus. Liquid lens variable autofocus technology is ideal for applications that require a large depth of field or when refocusing is needed after a product changeover.

The DataMan 300 intelligent tuning feature automatically selects the optimum settings for the integrated lighting and for the autofocus optics for each application. This tuning process ensures that the barcode reader will be set up to attain the highest read rates possible for 1D, 2D and direct part marked (DPM) codes. The liquid lens can also be adjusted with software or serial commands without having to touch the reader.

For presentation reading, tote scanning and small-package sorting applications, the liquid lens can be configured to dynamically sweep through the full focal range of the optics to find and read barcodes over a wide range of working distances.

DataMan 300 is available in two models: the DataMan 300 has a resolution of 800 x 600 pixels and the DataMan 302 has a higher resolution of 1,280 x 1,024 pixels. The DataMan 302 is ideal for reading very small DPM codes, often found in applications in the automotive and electronics industries.
