Code readers using a mechanical focus mechanism generally break due to deterioration of the drive
mechanism or motor when they perform autofocus tens of thousands of times. The V430-F Series, on the
other hand, uses a liquid lens that does not need a drive mechanism or motor, providing unlimited
autofocus and long life.
The liquid lens can fiexibly change its focal length by applying voltage to change the internal oil and water shape. (a in right figure) In addition, the V430-F Series precisely focuses on objects using the code search algorithm. (b in right figure)
