How Zygo delivers high-performance optics from an unmatched range of substrates

To make sure high-performance optical systems don’t crack under pressure, selecting the right material is not a secondary consideration, it is foundational. The substrate used for an optical window or mirror governs the system’s optical performance, thermal stability, and resilience under operational conditions. Zygo™, a global leader in precision optics, distinguishes itself through a material-agnostic capability, manufacturing from an exceptionally wide range of optical (and non-traditional) materials to ensure optimal performance for any application.

While many optical manufacturers routinely work with standard materials like BK7, fused silica, and a variety of flint glasses (useful for general-purpose visible-spectrum optics) Zygo goes far beyond the conventional. The company is as comfortable working with these everyday materials as it is with complex, specialty crystal and ceramic substrates that most other suppliers avoid. This capability is a core differentiator and a critical asset for customers requiring custom, high-performance solutions.

Zygo`s capabilities span commonly used materials and those that demand specialized knowledge and infrastructure. Materials such as germanium, nickel-plated aluminum, single- and polycrystalline silicon, sapphire, and zero-expansion ceramics like ZERODUR® and CLEARCERAM®-Z are all routinely handled at Zygo. Each of these materials serves a distinct purpose.
