Calculating Window Tilt Angle And Localization - Microscan MS-1 Integration Manual

Calculating Window Tilt Angle and Localization

External Window Tilt Angle and Placement
Use the following guidelines if a window will be placed between the front of the MS-1 and
the opening of a case or other enclosure.
Window Opening
Make the clear opening of the window large enough that the entire aperture width and
height passes through the window. It is recommended that you add an extra 5% tolerance
to the calculated height and width. Not allowing the full window opening can result in
potential internal reflections and can degrade the decodable depth of field range performance.
Window Tilt Angle
Calculate the tilt angle for the window based on the distance from the engine's aperture
exit point and the (zero degree) horizontal point of the window (inside edge), which is
distance Da. Further tilting of the window is acceptable and decreases the possibility of
specular reflection from that window, which can degrade the scan engine's performance to
the point that it may not decode at all.
