Matrix 120 readers are not designed to be used in real-time Laser Marking applica-
tions (Mark & Read). They must be mounted far away from the Laser Marker to avoid
burning the CMOS sensor.
CAUTION

Short Distance Code Reading on Reflective and/or Colored Surface

Matrix Wide Angle Polarizer models provide advantages in particular applications
which require codes to be read very short reading distances on reflective and/or
colored surfaces like black plastic and have 0° Skew angles.
