Matrix 300N also comes with a built-in polarizing filter. 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 300N with polarized illuminators features
e
xtreme 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 p
olarizing filters:
