Integrated liquid lens autofocus for barcode reader
available for pre-order featuring both automatic and software-programmable autofocus. Liquid lens autofocus technology has been offered in Microscan technology since the release of the company’s high-performance QX Hawk barcode imager in 2009. This technology uses electrostatic pressure to create electrical currents that react with the two liquids inside the lens to produce the appropriate lens curvature. This enables barcode imagers to read symbols at any distance and speed in any environment, including very large linear barcodes on packages.
