Vision-enabled barcode readers with the ease-of-use and cost of laser scanners

John Keating, 09-13-2011

Our optics and mechanical engineers are always evaluating new technologies. They are committed to bringing innovation to our products in order to simplify usability for our customers like you.

When the chose to add liquid lens technology to our already flexible portfolio of lens options for DataMan industrial ID readers, they made a great leap for our customers. The liquid lens simplifies installation, setup, and maintenance by eliminating the need to manually touch the lens to get it into focus.

There are lots of benefits of using the liquid lens: 

  • It provides a large range of focal length; 
  • It’s rugged because it has no moving mechanical parts; 
  • It provides good optical quality with fast response times; and 
  • It can operate in a wide range of temperatures and requires very little power.

Over the past couple of years, we were able to integrate variable focus liquid lens technology into both our Fixed-Mount Barcode Readers  and well as our Handheld Barcode Scanners
