(Cognex: Natick, MA) -- Cognex Corp., a global leader in industrial ID, 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 liquid lens is a very powerful addition to our DataMan 300 series of ID readers,” says Carl Gerst, vice president and business unit manager for ID Products. “The autofocus feature makes adjustment to different working distances as simple as pushing a button.”

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 1-D, 2-D, and direct part marked (DPM) codes. The liquid lens can also be adjusted with software or serial commands without having to touch the reader.
