Mounting the Scanner

16 Gryphon™ GFE4400

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.
