UPC 300

Ultra-precise machining of freeform optics



Introducing the UPC 300
The most accurate UPC 300 is a three axis machine (X, Z, C) designed for the highly dynamic machining of freeform surfaces. The optional long stroke Fast Tool significantly increases the productivity in freeform machining. The Fast Tool can process a wide range of freeform geometries without the need of time consuming Slow Tool machining - productivity and accuracy are combined in a very unique way.

An optional B-axis enhances the functionality to optimally support the machining of diffractive structures or high aperture angles.

A high-quality optical metrology system allows for the machine integrated contactless measurement of the entire freeform surfaces. In combination with the unique data handling capabilities a corrective remachining of freeform surfaces is possible to achieve highest precision.
