Illumination Examples for DPM Applications
The following images have been captured by a Matrix 300N DPM model reader to
demonstrate 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).

For correct use of the MLT-DPM Peripheral and LT-51x illuminators, make sure that
the application working distance is within the lighting system working distance. See
the table under “Lighting System Working Distances” on page 207.
