Matrix 320 also comes with a polarizing cover. This is the ideal solution to reduce hot
spots on reflective surface applications, such as:
• DPM on reflective metal surfaces
• DPM on non-metal reflecting surfaces
• DPM on electronic circuit boards
• Glossy labels
• Labels under plastic films
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:
