We achieved a flatness of 1 micron by thermal spraying alumina-based ceramics onto a standard granite surface plate and precision grinding and lapping the surface. This surface plate also boasts five times the wear resistance compared to conventional granite surface plates. It is possible to either manufacture a new "i Flat" or convert your existing granite surface plate into an "i Flat" by thermal spraying ceramics onto it.

It goes without saying that high-precision measurements require a high-precision measuring surface. However, a common stone surface has the drawback of wearing out quickly. Additionally, ceramic surfaces can be very expensive. Therefore, by attaching "Abso Flat" to your existing stone surface, you can achieve long-term high-precision measurements with less wear, while also significantly reducing costs compared to ceramic surfaces.
