Large Reference Flats on Rotary Polishing Machine
A double-sided reference flat, where both sides are polished to specification, may also be used as a reference surface for evaluating a test optic, or it may be used as a optical window, or as oil-on plates for material qualification, such as optical homogeneity.
ZYGO can fabricate custom reference flats from a wide range of materials, including, but not limited to:
• Cleartran (water-clear Zinc Sulfide - ZnS)
• Sapphire (various crystal orientations)
• Zinc selenide (ZnSe)
SizesZYGO can fabricate reference flats ranging in size from a few millimeters to greater than 1 meter.
WavelengthsZYGO has developed a wide range of manufacturing processes to fabricate reference flats and windows 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. Reference flats can be provided with or without thin film coatings.
