Varying the polishing speed and length of stroke combined with our recipe for polishing and grinding a lens results in perfection. That means taking as much time as needed—as much as 16 hours or more—to achieve the highest accuracy, with optical elements as large as 609 mm in diameter. Our processes feature a Grinding House where shaping, generating, grinding, polishing and edging operations are performed and where our various machines produce surface configurations true to 1/20th of a wave. Our engineers and applications apply their expertise and feel in grinding and polishing each lens to hit the tough specs.
