Optics
The EM3080-W V2 uses a sophisticated optical system. An improper enclosure window material will have an influence on
the performance of the engine.
Window Placement
Properly place the window in order to prevent reflection back into the engine. If the enclosure can't meet the recommended
window angle, contact Newland to discuss positioning matters. Improper position will dramatically affect the performance.
There are two alternatives to position the window.
• Parallel - The window should be positioned properly to let the illumination beam pass through as much as possible and
no reflections back into the engine.
The window should be mounted close to the front of the engine (parallel). The maximum distance is measured from the
front of the engine housing to the farthest surface of the window. In order to reach better reading performance, the distance
from the front of the engine housing to the furthest surface of the window should not exceed 3mm and the distance from the
front of the engine housing to the nearest surface of the window should be less than 1mm.
For the window distance, please see Figure 2-4.

• Tilted - This is for laser or imager engines. For the window distance, please see Table 2-2.
