Integrating the Scanner Behind a Window
It is recommended to conduct scan performance testing with any window
to determine if the performance level is acceptable for the application.
•
Window material should be transparent with
92% transmission
to wavelength 625nm and 850nm.
•
Only a flat window must be used.
•
The window should be as thin as possible (thickness less than
2mm).
•
The window should be as close to the illumination LEDs as possi-
ble to avoid LED ghost images or light reflections. Tilting the
window and/or anti-reflective coating can help mitigate illumina-
tion reflections.
Performance degradation may include:
•
The scan module will not read very low contrast labels.
•
The scan module will not be able to wake up, especially in low
ambient light (typically <100Lux). In this case, the scan module
may need its wakeup sensitivity setting increased.
CAUTION
The addition of a host enclosure window could
degrade scanner performance. This is due to the
optical reflective surfaces that will cause interfer-
ence with the imaging technology.
