window placement
The installation of the window should be as close to the front of the WSM-QL1601 module as possible, and
parallel to the front plane of the module, so that the illumination beam and the aiming beam can be emitted as much
as possible, and the reflection into the module should be prevented. If the beam is reflected into the module, the
reading of the module will be reduced. performance . Therefore, it is recommended that the vertical distance between
the near-end surface of the window and the module should not exceed the value of a (a=0.6mm), and do not touch
the surface of the module. At the same time, please ensure that the thickness of the window does not exceed 2mm .
The gap between the front of the module and the proximal end of the window is used to protect the module and
window from external shocks when dropped .
If the window needs to be inclined, the distance requirements are the same as those of parallel installation, and
the inclination angle should ensure that there are no various beams of reflective lenses to ensure the reading
performance .

Window Material Color and Scratch Resistant Coating
Since the module adopts the image acquisition method for reading, the window material and color selection
should consider materials with high light transmittance, low ambiguity and uniform refractive index . At the same
time, scratches and dirt on the window will reduce the reading performance. It is recommended that the window be
designed to be scratch-resistant and dirt-resistant .
