Reading all barcodes, first time, every time is the most important thing to the worker, so a barcode reader that can adapt to the circumstances and "just read the barcode" allows the user to concentrate on the work, not on the kit.
The problem is that until recently barcode scanners were nowhere near as good as the human eye at reading at a distance or close up, a bit like when we get older and need both reading and distance glasses (like me).
Until now that is! Now an amazing new technology that uses a solid state "liquid lens" and refocusses in milliseconds has been built into the latest Datalogic PowerScan 9500 HP industrial barcode readers.
What does this mean? Well it means that this barcode scanner can refocus on the barcode at different distances, just like a (young) human eye. Do you remember as a child being surprised that Grandpa needed glasses to read and different glasses for everything else?
And now for the science: Using a technique called Electrowetting the lens is focused using an electric field to reshape a special oil/water lens cell. There are no moving parts and the cell is totally sealed, only the internal liquids change shape.
This gives the lens fantastic shock resistance and a focal length from 5cm to infinity, perfect for reading small barcodes near to and large barcodes far away. Ideal for a warehouse or loading yard, where the operator needs to read barcodes on a loading sheet and racking bays or pallets.
