Aiming Pattern
Aiming indicates the appropriate reading distance by projecting a bar of green LED light:
•
The optical axis of the imaging field of view and the center of the horizontal aiming bar
coincide at a distance of L=148±20 mm from the front edge of the imager scanner.
•
The width of the aiming bar at a distance of L=148 mm is 90%±10% of the width of the
horizontal field of view.
•
The sharpest aiming bar distance is 113 ± 10 mm (SR models), 63 ± 10 mm (HD
models), or 43 ± 10 mm (UD models).

Image Range
The image range is the imaging field of view (not the scan area).
Image Range for SR Models
L: Distance from the Front Edge of the
Imager Scanner (mm)
Horizontal Field of View (FOV)
Vertical Field of View (FOV)
Note: The range is ±5% from these values.
Image Range for HD Models
L: Distance from the Front Edge of the
Imager Scanner (mm)
Horizontal Field of View (FOV)
Vertical Field of View (FOV)
Note: The range is ±5% from these values.
