Parameters
Reference values for reading distance - reading field size - resolution
Maximum reading distance with minimum resolution
Skew angle, depending on the application
should typically be tilted by 20° out of the perpendicular in relation to the surface of the
code to avoid disruptive reflections.
In the case of codes created on metal, e.g., by dot peening, an angle of between 0° (bright
field light) and 45° (dark field light) may be advisable.
