Precision Optical Windows

ZYGO is trusted worldwide to provide optical windows for the most high-precision, advanced applications. For over 45 years, we specialize in bringing the most challenging optical designs to life. ZYGO works as your design partner, ensuring you receive windows meeting your most stringent specifications.

An optical window is a polished piece of material that is transparent at some portion of the electromagnetic spectrum, which allows the desired portion of the spectrum to pass into an optical instrument unaltered.

 "The tight tolerances of the large window that Zygo produced for us are impressive – our 6” sub-aperture wavefront error spec was achieved across the entire 16” window. Thank you for the high-performance optic." - BAE Systems

The ZYGO Advantage

ZYGO's optical windows are created using stringently controlled fabrication processes, allowing them to function reliably in a variety of extreme environments. ZYGO windows are found underwater, in deserts, at high altitudes and orbiting the earth.

Some common types of windows we produce include:

  • Conformal Windows
  • Debris Shields
  • Laser Windows
  • Metrology transmission flats
  • Periscope Windows
  • Vacuum Windows
  • Viewports
We customize every optical window to meet or exceed your requirements. The windows we create are unique, requiring cutting-edge fabrication technologies. ZYGO's proprietary processes allow us to create optical windows meeting challenging specifications, such as:
  • Sizes up to and exceeding one meter diameter
  • Advanced thin film coatings
  • Excellent transmitted wavefront error
