Matrix 320 also comes with a polarizing cover. This is the ideal solution to reduce hot
spots on reflective surface applications, such as:
•
•
•
•
•
By removing LED reflection, Matrix 320 with polarized illuminators features extreme
mounting flexibility, as it can be mounted 90° to the target surface. This in turn avoids
code distortion and allows more reliable code grading.
The following examples show the difference between codes read with and without
polarizing filters:
DPM on reflective metal surfaces
DPM on non-metal reflecting surfaces
DPM on electronic circuit boards
Glossy labels
Labels under plastic films
DPM: Data Matrix
Non polarized
on electronic components
