FLASH™ Dynamic Focus:
The DS6400 has an innovative linear motor designed to control the focus position of the scanner via software.
This dynamic system, called FLASH™, is able to move the focus position rail to rail, from the minimum position to
the maximum position.
The FLASH™ functionalities (i.e. the driving modes of the linear motor) are programmed via the Genius™
software tool and can operate in the following modes:
- Fixed
mode: the focus is set to the desired position via software (expressed in cm);
- Continuous mode: the focus position is continuously running from a minimum position to a maximum position
with a defined frequency;
- Triggered
mode: the focus position can be set depending on the received external input (photocell, barrier,
serial message, etc.);
- D-Flash™
mode: the focus position can be set depending on the measured distance between the scanner
and the scanned object. This is the most innovative and flexible function that makes different software
implementations possible. The D-Flash™ development has been based on the minimum distance detected.
Thus, it can apply to the
widest variety of applications. Further developments of D-Flash™ will be provided
according to the specific application needs.
