The Sonar TechnologyTM works with an ultrasonic sensor on the laser head. This sensor enables a very precise distance measurement on every position of the working table. With only one press of the button on the keyboard, the focus point is calculated automatically based on the lenses selected in the software. The working table moves to the optimum focus position automatically.
This focus mode is particularly suited for all sound reflecive materials. Being flexible and user friendly the Sonar TechnologyTM is a very efficient focus mode. Patent is pending.
