Flat optics can be fabricated in a variety of geometries, including round, square, rectangular, and free-form. Cubes and prisms are also classified as flat optics. Flat optics have a wide variety of applications, including windows, mirrors, filters, transmission optics, reference optics, and wedges. ZYGO can produce flat optics ranging in size from a few millimeters to greater than 1 meter.

A world-leading manufacturer of high precision flat optics, ZYGO employs innovative and proprietary optical manufacturing technologies, including CNC glass machining and lightweighting, rotational, double sided, and MRF polishing, and thin film coating.

ZYGO has the distinction of being the world's only volume manufacturer of laser fusion amplifiers and a world recognized producer of meter-class flat optics, including high aspect ratios and advanced materials such as water free zinc sulfide and sapphire.


ZYGO can fabricate flat optics from a wide range of materials, including, but not limited to:

Cleartran windows (water-clear Zinc Sulfide - ZnS)

Germanium windows

Glass windows (fused silica, BK7, etc.)

Sapphire windows (various crystal orientations)

Silicon windows

Zinc selenide windows (ZnSe)


ZYGO has developed a wide range of manufacturing processes to fabricate flat optics that operate in the infrared (IR), visible, and ultra-violet (UV) parts of the spectrum. Similarly, ZYGO has experience with multi-spectral applications, combining IR and visible. Flat optics can be provided with or without thin film coatings


ZYGO has a long tradition of manufacturing custom-made flat optics for a wide variety of applications, including, but not limited to:

• Amplifier Slabs, discs and rods

• Debris Shields

• Infrared (IR) windows

• Intelligence, surveillance & reconnaissance (ISR applications)

Laser fusion optics

• Reference surfaces

• Ultra-violet (UV) windows

• Visible windows
