|Cast Iron Surface Plates
We offer standard 12 '' x 18 '' cast iron surface plates in two
Cast iron surface plates (used as surface master) for calibration of
our systems for large sample applications.
Cast iron is more dimensionally and geometrically stable over time
than granite or ceramics and is more easily worked to a higher
grade of flatness. It provides more uniform optically surface free of
color and refractive index variation characterizing granite plates.
