This DPM Adapter combines diffused illumination with the buit-in magnifying lens, which makes it very efficient for reading very smal DPM Marks (3-5 mils). Though the DPM Adapter is designed for SR/ER versions it performs well for the HD version, as well. Reading technique for the “Scanner + Adapter” requires Adapter to be put in contact with the sample.
Xenon 1900/1902GER with DPM Adapter demonstrates reliable decoding of very small Data Matrix symbols that have module size as small as 2.8 mils ("paper" labels), thus increasing effective resolution of the scanner by 2-3 times:
|Sample Description||Image captured by|
