2 - 14 Symbol MiniScan MSXX07 Series Integration Guide

Embedded Window Angle and Position

If a window is placed between the MiniScan and the item to scan, observe the following guidelines:
•
Window Clear Opening - Make the clear opening of the window large enough so that the entire scan beam
passes through the window. Cutting off any part of the beam can result in internal reflections and degrade
decode range performance. Ensure that window placement relative to the MiniScan accounts for tolerances
on all parts involved in that assembly.
•
Window Angle - Angle the window at least 2o more than the tilt of the window on the scanner (see Tabl e
2-4). Further tilting the window is acceptable and decreases the possibility of a secondary reflection from that
window degrading the scanner's performance.
•
Optical Working Range - Adding a window can reduce the working range of the scanner since there is a
signal loss when passing through window material. To minimize this reduction, use a special coating
described in Window Coatings on page 2-13. To understand the difference, test the scanner in the desired
orientation and see if the difference affects scanner performance.
