Description
原型は、機械加工可能な金属からなる厚さ約1インチのブロックに直径9インチ(22.86cm)を用いて形成された。ブロックは、約0.005インチ(0.127mm)だけ盛り上がった4.75インチ(12.06cm)の正方形部分を有するように機械加工された。ブロックは、少なくとも±100nmの正確さの溝間隔および溝深さの精度(すなわちポイントツーポイント位置決め)および少なくとも±10nmの解像度(すなわち現在の軸位置を検出するためのレーザ干渉計位置決め装置の性能)を有するように溝形成装置に配置された。
比較例Aの再帰反射シートのコーナキューブ面は、厚さ950オングストロームで蒸着することによってアルミニウムでコーティングされた。
原型は、比較例Aに記載されたものと同一の態様で形成された。ポジティブコピー成形型は、その成形型からシートを形成するために用いられた。このネガティブコピーシートのコーナキューブ構造面は、蒸着によってアルミニウムでコーティングされた。
