DZr-P Zirconia Slurry
DZr-P Zirconia Slurry
Demeter Technologies Inc., United States
Demeter Technologies' zirconium oxides have been developed to produce very fine surface finishes on a variety of glasses and ceramics. Statistical process control ensures consistent particle hardness for high stock removal rates. Our proprietary classification process produces narrow particle size distributions that give our slurries high surface quality with no scratching. Zirconium oxides can be supplied in powder or slurry form. Custom formulations are available.

Test Plates
Test Plates
Rainbow Research Optics Inc., United States
Test plates are used as a reference to test surface flatness, power, displacement, irregularity, and radius of curvature. Before interferometers were so widely used, test plates were the only method for optics fabricators to verify the flatness of a particular optical surface.
