The Alta Evolution is equipped with Gravitech®, a revolutionary new optical tracing system. With the help of a camera, this unique tracer can accurately trace a demo lens and project it in 3D in under 4 seconds. 

Ideal for finishing labs in cramped quarters: the compact design of the unit was designed to save space without sacrificing quality. An intuitive touch screen interface makes operation of the unit simple and efficient. The unit adheres to OMA/VCA communication protocols which allows the Alta Evolution to interact with a wide array of edging equipment.
