• Flatness better than λ/40.
• Surface Roughness < 1nm.
• Sizes up to 32" can be measured at full aperture.
In addition to reference and transmission flats, ZYGO manufactures oil-on plates for material qualification. Our large polishing machines allow us to manufacture not only round optics to over a meter in diameter, but in addition we supply reference bar mirrors for use in semiconductor manufacturing, or wherever the most precise measurements are required.
SizesZYGO can fabricate optical flats ranging in size from a few millimeters to greater than 1 meter.
WavelengthsZYGO has developed a wide range of manufacturing processes to accommodate optical flats 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 flats can be provided with or without thin film coatings
MaterialsZYGO has the capability to process a wide range of materials for precision optical flats, including, but not limited to:
• Cleartran (water-clear Zinc Sulfide - ZnS)
• Glass (fused silica, BK7, etc.)
• Sapphire windows (various crystal orientations)
