Large Optical Flats, Optical Flat Polishing Machine
A double-sided optical 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.
• Cleartran (water-clear Zinc Sulfide - ZnS)
• Sapphire (various crystal orientations)
• Zinc selenide (ZnSe)
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 fabricate optical 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. Optical flats can be provided with or without thin film coatings.
ApplicationsZygo has a long tradition of manufacturing custom-made optical flats 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)
• Ultra-violet (UV) windows
• Visible windows
