Definition: Focus is the act of narrowing the focal spot to its smallest size and
sharpest edges at the desired distance from the scanner by moving an
internal lens in discrete movement with a stepper motor.
Focus Position is the length of the internal lens.
Usage: Focus is generally done by the Autocalibration routine (see Chapter 6,
Autocalibration”). However, in certain applications involving specific
focal lengths, manual control of focus might be appropriate.
Serial Cmd: <K508,focus position,zero position>
Default: 10 (inside focal length)
Options: 0 to 40 (nearest to furthermost focal length)
Definition: This field displays the current factory-set zero focus position.
Usage: This field is READ ONLY, and is set by a qualified technician during fac-
tory setup.
Serial Cmd: <K508,focus position,zero position>
