Illuminators

Matrix 300N
An orange filter is applied over the
Central LED Group
in order to avoid harmful
blue light reflections off the
Peripheral LED
component packages.
The
Peripheral LED Group
can also be used as a Bright Field illuminator in the
range from 50 to 100 mm. This group is similar to the
Diffused Red Illuminator
Peripheral LED Group
but differs by the light intensity (lower in the
MLT-DPM
)
and wavelength emitted by the LEDs.

Like the Diffused Red Illuminator, in software each single sector can be turned
on, however it is NOT possible to simultaneously turn on sectors belonging to
the separate LED Groups - Peripheral and Central. Despite this restriction, thirty
different combinations of ON/OFF lighting configurations can be obtained.
By enabling multiple Image Settings,
each having a different ON/OFF LED
combination, different consecutive images can be acquired, changing the
activation of the eight LED sectors. This feature is particularly effective for
reading codes printed/marked on reflective surfaces, by sequentially turning OFF
the single LED sectors.
