Housing Design
Design the housing so that internal reflections from the illumination system are not directed back toward the
engine. The reflections from the window can cause problems, and for particular window tilt angles, these
reflections can bounce off the top or bottom of the housing and reach the engine.
The Exit Window Information (Figure 2-2 on page 2-6) provides minimum exit window dimensions and tilt angles.
These dimensional requirements can vary. Consider using matte-finished dark internal housing colors.
Optical
The Symbol SE6700 uses a sophisticated optical system that provides imaging performance that matches or
exceeds the performance of much larger imagers. However, the performance of the SE6700 can be affected by an
improperly designed enclosure, or improper selection of window material.
Positioning the Exit Window
Position the window so that illumination system light reflected off the inside of the window is not reflected back into
the engine (see Figure 2-2 on page 2-6). The specified angle is the minimum; allow for manufacturing tolerances. If
the designed enclosure cannot accommodate the recommended window angle, contact Motorola to discuss
positioning requirements. An improperly positioned window can significantly decrease performance.
Avoiding Scratched Windows
Scratches on the window can greatly reduce the performance of the imaging system. We recommend recessing
the window into the housing or applying a scratch resistance coating.
NOTE Opto-mechanical analysis is recommended for housing design to ensure optimal scanning or imaging
performance.
