Polysiloxane Coating
Apply polysiloxane type coatings to plastic surfaces to improve the surface resistance to both scratch and
abrasion. Typically, you apply these by dipping, then air-drying in an oven with filtered hot air.

Embedded Window Angle and Position

If you are placing a window between the MiniScan and the item to image, observe the following guidelines:
•
Window Clear Opening - Make the clear opening of the window large enough so that the entire imager field
of view passes through the window. Cutting off any part of the field of view can 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 2
•
Further tilting the window is acceptable and decreases the possibility of a secondary reflection from that
window degrading the imager's performance.
Optical Working Range - Adding a window can reduce the working range of the imager 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
orientation and see if the difference affects imager performance.
