Germanium windows, opaque in the UV and visible parts of the spectrum, have a broad transmission range and are well-suited for IR applications. Germanium is a very hard, high-density material - characteristics that are advantageous where robustness is needed. Germanium's high density also makes it heavy, something to be considered when designing it into optical systems where weight is a consideration. Another characteristic of Germanium is thermal runaway, which means that its transmissive properties decrease as temperature increases.

Applications

ZYGO has a long tradition of manufacturing custom-made optical windows, in a wide variety of materials, for many different applications applications, including, but not limited to:

• Amplifier Slabs, discs and rods

• Debris Shields

Laser fusion optics

• Reference surfaces

Defense/Aerospace

Medical/Life Sciences

Industrial OEM

• Intelligence, surveillance & reconnaissance
(ISR)

Wavelengths

ZYGO has developed a wide range of manufacturing processes to accommodate optical windows operating 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. Optical windows can be provided with or without thin film coatings.

Sizes

ZYGO can process these types of windows for components ranging in size from a few millimeters to greater than 1 meter.

Materials

In addition to Germanium windows, ZYGO has the capability to process a wide range of materials to fabricate optical windows. Other materials for optical window products include, but are not limited to:

Cleartran windows (water-clear Zinc Sulfide - ZnS)

Glass windows (fused silica, BK7, etc.)

Sapphire windows (various crystal orientations)

Silicon windows

Zinc selenide windows (ZnSe)
