Illumination Examples for DPM Applications
The following images have been captured by a Matrix 220 DPM model reader to demon-
strate positioning and contrast considerations for DPM applications.
Code Positioning with Respect to Illumination
Since the various internal illuminators on the DPM models are located above or below
the sensor, the light emitted from them can cause glare in the respective area of the
image. If this glare covers the code, the reader will not be able to see it and therefore
cannot decode it (see the first image in the table below).
