High Technology Barcode Readers Now Available
Microscan, a global manufacturer and pioneer of auto ID solutions from the world’s first laser diode barcode scanner to the Data Matrix symbol, has launched fully-integrated liquid lens autofocus models of MicroHAWK® Barcode Readers. They are now available for pre-order “featuring both truly-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, from high-density 3.3 mil Data Matrix symbols on complex PCBs, to very large linear barcodes on packages, to low-contrast direct part mark (DPM) symbols on machined parts. 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.

When using a MicroHAWK autofocus unit in “triggered mode” (the unit waits for a command or signal before locating a symbol and capturing an image), users can do a quick focus by selecting the Autofocus button from the WebLink user interface and then clicking anywhere within the live view to set the reader’s focal distance for specific code locations. Users can also manually adjust the reader’s focus while in triggered mode using controls in the WebLink interface to set specific distances in inches or millimeters. When using a MicroHAWK autofocus unit in “continuous mode” (the unit actively locates symbols to decode), users can select and deselect the Autofocus button to switch from active autofocus to fixed focus. With the Autofocus button selected, a MicroHAWK reader will continue to search for a symbol within its field of view at a given focal distance, adjusting focus after a set number of no-read results to search for a symbol at another focal distance. This truly-automatic autofocus capability offers both integration simplicity and peace of mind that MicroHAWK will reliably decode despite variable barcode locations and positions without manual intervention.
