Straight Edges
Straight edges are precision machined and polished structures used as a physical or optical reference surface. ZYGO manufactures extreme precision straight edges from low CTE (coefficient of thermal expansion) materials, achieving tolerances up to 1,000 times better than a machinist’s straight edge. Fabrication, coating, and metrology are all performed by ZYGO. Ask us about high volume / OEM pricing options.
