10.2 Scan Area and Depth of Field
The scan area is measured from the front edge of the imager scanner. The depth of field
depends on the view angle and symbol length. Depth of field values provided are the typical
values measured by tilting the test chart 15° from the optical axis.
The focal point of the camera, and therefore the depth of field, is different for the SR, HD, and
UD models. This section describes the depths of field for all three models.
