An optical windows 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. Some common types of windows we produce include:
• Conformal Windows
• Debris Shields
• Laser Windows
• Metrology transmission flats
• Periscope Windows
• Vacuum Windows
• Viewports
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.
