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.
Liquid lens autofocus not only enables flexible positioning within machines and other integration environments, it eliminates the need for automation engineers to research multiple configuration options before choosing a reader for an application. Microscan integrates its liquid lens technology directly into its highest-performance imaging platforms rather than requiring add-on optical accessories, eliminating additional cost, device size, and integration complexity.
