The Lava COS wand contains a highly complex optical system comprised of multiple lenses and blue LED cells. The system captures massive amounts of visual images in just seconds. Despite housing all of this technology, the wand weighs just 14 ounces and the wand tip is only 13.2 millimeters wide, maximizing maneuverability inside the mouth.
The Lava COS is introducing an entirely new method of capturing 3D data. Called High Speed Image Processing Algorithms, this 3D-in-Motion technology captures 3D data in a video sequence and models the data in real time. Thus, the Lava COS is able to capture approximately 20 3D data sets per second, or close to 2,400 data sets per arch, for an accurate and high speed scan. Unlike video imaging, point and click uses a sequence of individual "snapshots" to assemble a model.
While capturing massive amounts of data is quite an accomplishment, an even more impressive achievement is the ability of the Lava COS to model that data in real time. Unlike other systems on the market today, the Lava COS simultaneously displays the images that are being captured in the mouth onto the touch screen monitor. With this real-time visibility, a dentist can confidently and immediately assess whether enough information has been captured for a complete digital impression. The COS data is sent to the laboratory for review and processing before forwarding to a central manufacturing plant where the models are produced using stereolithography as opposed to milling.
