Double safe

Before the lasers will be switched on the positioning of the laser modules are double-checked by use of two technically independent procedures.


Red laser diodes have been established on the market for more than 30 years, and have an operating life of over 30,000 hours.


Depending on your workflow, you can choose whether the coronal laser line can also be traversed in addition to the sagittal. 

Comfortably moveable

You can control the movable lasers either on-the-move via the tablet PC, or via the desktop PC in the control room.

Easy to calibrate

The movable and fixed lasers in your DORADO system can be manually fine-tuned with the supplied Wilke phantom.

Consistently precise

For consistent laser line precision over the entire 700 mm travel range, the mechanical components are manufactured to be virtually tolerance free and coordinate perfectly with one another.

Configurations of DORADO

DORADO 1 Laser System for Patient Marking


For precise patient alignment and easy marking, you can move the sagittal laser line. The transversal and coronal body planes are projected via fixed lasers.

DORADO 3 Laser System for Patient Marking


The two movable sagittal and coronal lines allow our laser system to offer increased flexibility for marking and virtual simulation. The transversal body plane is projected via fixed lasers.
