Housing Design

NOTE Perform an opto-mechanical analysis for the housing design to ensure optimal scanning or imaging
performance.
Design the engine's housing so that internal reflections from the aiming and illumination system are not
directed back toward the engine. The reflections from the window or housing 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. Also, keep all housing elements outside the imaging field of view and usable illumination volume (see
Figure 2-2 on page 2-7
reflected by a tilted window into the engine field of view and appear in a captured image.

dimensional requirements can vary. Consider using baffles or matte-finished dark internal housing colors.

Optical

The SE3300 uses a sophisticated optical system that provides imaging performance that matches or exceeds
the performance of much larger imagers. However, an improperly designed enclosure, or improper selection of
window material, can affect the performance of the SE3300.

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
accommodate the recommended window angle, contact Motorola to discuss positioning requirements. An
improperly positioned window can significantly decrease performance.
Tilted Window
Use a tilted window for window positioning. Adhere to the minimum window tilt specifications in
page
2-9. With tilted window installation, 2-sided anti-reflection coating is optional (see
