Specifications for the Supplemental Window
In applications where a secondary window is installed with the IS4125, the
following recommendations should be followed in order to achieve the best
performance. While these recommendations provide general guidelines for a
successful integration and installation, it will take some testing to find exact
parameters to optimize scan performance and auto detection in each application.
The window should be tempered or chemically strengthened glass.
The window should be of optical quality and have a transmission of 98%
or greater between 600 nm – 700 nm.
The window should be optically flat, clear, and free of inclusions,
scratches and pits.
The window should not have birefringence.
The window should have an anti-reflective coating on both sides to
minimize "ghost" images or reflections.
The window should not be thicker than 2.0 mm.
The window and the engine should be mounted in a way to avoid direct
reflections of both the laser beam and LED of the object detection from
hitting the scan engine.
The angle between the window and the engine should be approximately
15° to 20°, but should be adjusted as needed. See Figure 6.
Figure 6. Supplemental Window Angle
In rare instances where a supplemental window was previously installed and the
factory default long range is enabled, the new object detection mechanism may
behave differently. If this occurs, scan the

bar code below to configure the engine to short range object detection.
