Prons and Cons
DisadvantageIf +/-1um feature accuracy of the calbiration board/target is essential (System accuracy<=10um), high resolution printing on carbon fiber is not an option;
Advantage Sharp Feature Edgecarbon.jpg
Rigid and Stable in surface flatness, carbon fiber board does not bend or curl on the surface and corners compared with aluminium board during use;
 Diffuse reflectance surface, no glare with on or off front lighting, also no glare for outdoor applications;comparison 01.jpg
